Perinatal outcomes between immediate vs deferred selective termination in dichorionic twin pregnancies with fetal congenital anomalies: a French multicenter study.

BACKGROUND: Because selective termination for discordant dichorionic twin anomalies carries a risk of pregnancy loss, deferring the procedure until the third trimester can be considered in settings where it is legal. OBJECTIVE: To determine whether perinatal outcomes were more favorable following deferred rather than immediate selective termination. STUDY DESIGN: A French multicenter retrospective study from 2012 to 2023 on dichorionic twin pregnancies with selective termination for fetal conditions, which were diagnosed before 24 weeks gestation. Pregnancies with additional risk factors for late miscarriage were excluded. We defined 2 groups according to the intention to perform selective termination within 2 weeks after the diagnosis of the severe fetal anomaly was established (immediate selective termination) or to wait until the third trimester (deferred selective termination). The primary outcome was perinatal survival at 28 days of life. Secondary outcomes were pregnancy losses before 24 weeks gestation and preterm delivery. RESULTS: Of 390 pregnancies, 258 were in the immediate selective termination group and 132 in the deferred selective termination group. Baseline characteristics were similar in both groups. Overall survival of the healthy co-twin was 93.8% (242/258) in the immediate selective termination group vs 100% (132/132) in the deferred selective termination group (P<.01). Preterm birth <37 weeks gestation was lower in the immediate than in the deferred selective termination group (66.7% vs 20.2%; P<.01); preterm birth <28 weeks gestation and <32 weeks gestation did not differ significantly (respectively 1.7% vs 0.8%; P=.66 and 8.26% vs 11.4%; P=.36). In the deferred selective termination group, an emergency procedure was performed in 11.3% (15/132) because of threatened preterm labor, of which 3.7% (5/132) for imminent delivery. CONCLUSION: Overall survival after selective termination was high regardless of the gestational age at which the procedure was performed. Postponing selective termination until the third trimester seems to improve survival, whereas immediate selective termination reduces the risk of preterm delivery. Furthermore, deferred selective termination requires an expert center capable of performing the selective termination procedure on an emergency basis if required.

The Role of Midwives in US Perinatal Palliative Care: A Scoping Review.

INTRODUCTION: Perinatal palliative care (PPC) is a rapidly growing and essential reproductive health care option for pregnant persons with a diagnosed life-limiting fetal condition who continue their pregnancy. The provision of PPC is within the scope of basic midwifery competencies, and midwives are well-positioned to make unique and valuable contributions to interprofessional PPC teams. However, little is known about midwives' past or current involvement in PPC in the United States. METHODS: This scoping review of the literature investigated what is known about the role of midwives in PPC in the United States. Multiple databases of published literature were used for this review: PubMed, CINAHL, Embase, Web of Science, ProQuest, Google Scholar, and relevant citations from identified studies. All types of English language publications addressing midwives' involvement in PPC in the United States were included, without any limitations on publication date. RESULTS: The role and contributions of midwives in PPC is not well represented in existing literature. Of the 259 results identified, 7 publications met criteria for inclusion. These included 5 case reports, one quantitative research article, and one conference abstract. Midwives are involved in PPC through the provision of direct clinical care (including antepartum, intrapartum, postpartum, neonatal, bereavement, postmortem, and follow-up care) and care planning and coordination as part of an interprofessional team. DISCUSSION: Despite midwives being uniquely positioned to provide holistic, family-centered, and person-centered care in situations of pregnancy with life-limiting fetal conditions, there is limited literature about their involvement in PPC in the United States. PPC should be incorporated into midwifery education and training programs. Midwives should play a central role in shaping future research and policies to ensure the accessibility and quality of PPC.

The prevalence of congenital anomalies: nationwide study in 2020 in Estonia.

OBJECTIVE: To assess the prevalence of congenital anomalies (CAs), chromosomal abnormalities and monogenic diseases among births and terminated pregnancies due to fetal anomalies (TOPFA) in 2020 in Estonia. Up to 2020 no data on prevalence of CAs in Estonia is reported. METHODS: For retrospective observational study data of all births and terminations of pregnancies after 12th gestational week from (i) the Estonian Medical Birth Registry, (ii) Abortion Registy, (iii) Health Insurance Fund and (iv) hospital records were linked. To calculate the total, live birth, stillbirth and TOPFA prevalence of CAs with 95% confidence intervals (CI), guidelines issued by EUROCAT, European network for the epidemiological surveillance of CAs, https://eu-rd-platform.jrc.ec.europa.eu/eurocat_en were followed. RESULTS: In 2020 the total prevalence of CAs, chromosomal abnormalities and monogenic diseases in Estonia was 378.6 per 10,000 births (95% CI 346.0, 413.5). The most prevalent CAs were heart defects, 163.7 cases per 10,000 births (95%CI 142.5, 187.2). The prevalence of chromosomal abnormalities and genetic diseases was 92.6 per 10,000 births (95%CI 76.8, 110.6), 80% of cases were among TOPFAs. No newborns with major aneuploidies (Trisomy 21, 18, 13, polyploidy) were reported in 2020. Live birth prevalence of CAs, including chromosomal abnormalities and genetic diseases was 258.4 per 10,000 live births (95%CI 231.5, 287.5) and stillbirth prevalence of CAs 0.8 per 10,000 births. CONCLUSIONS: The prevalence of CAs and genetic disorders in Estonia is one of the highest compared to prevalence reported by other European regions. It indicates to high population coverage with prenatal diagnostics in Estonia. Low number of major aneuploidies among live births may reflect good detection rate of major chromosomal abnormalities and cultural preferences.
