Data Sources: PubMed, Scopus, Cochrane Library, ClinicalTrials.gov, and CINAHL (EBSCO) were searched from inception to December 2023.

Recombinant erythropoietin for the treatment of iron deficiency anemia in pregnancy: A systematic review.

Background: Treatment options for severe, refractory iron deficiency anemia are limited in pregnancy.

Objective: To review the available literature on the use of recombinant erythropoietin in the treatment of iron deficiency anemia in pregnancy.

Search Strategy: An electronic search of seven databases from inception to March 2022 was performed using a combination of keywords.

DNA methylation patterns in umbilical cord blood from infants of methadone maintained opioid dependent mothers.

Methadone maintenance treatment for opioid dependent mothers is standard of care. Infants of methadone maintained opioid dependent (MMOD) mothers have better outcomes compared to infants of opioid dependent mothers without treatment. However, when compared to non-exposed infants, infants of MMOD mothers are associated with worse outcomes.

Glucose-6-phosphate dehydrogenase deficiency as a cause for nonimmune hydrops fetalis and severe fetal anemia: A systematic review.

Background: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an X-linked recessive disorder that predisposes individuals to hemolysis due to an inborn error of metabolism. We performed a systematic literature review to evaluate G6PD deficiency as a possible etiology of nonimmune hydrops fetalis (NIHF) and severe fetal anemia.

Methods: PubMed, OVID Medline, Scopus, and clinicaltrials.

Antenatal steroids and neonatal outcomes in late preterm births with pregestational diabetes.

Objective: To evaluate if antenatal steroid use was associated with a lower rate of respiratory complications in neonates born late preterm to patients with pregestational diabetes mellitus (PGDM).

Methods: This was a retrospective cohort study of live, singleton, non-anomalous, late preterm births complicated by PGDM using data from the Centers for Disease Control and National Vital Statistics System from 2017 to 2021. The primary (assisted ventilation use >6 h) and secondary neonatal outcomes (immediate assisted ventilation, Apgar score, neonatal intensive care unit [NICU] admission, and surfactant use) were compared between births that received steroids and those that did not.

The genetic etiologies of bilateral renal agenesis.

Objective: The goal of this study was to review and analyze the medical literature for cases of prenatal and/or postnatally diagnosed bilateral renal agenesis (BRA) and create a comprehensive summary of the genetic etiologies known to be associated with this condition.

Methods: A literature search was conducted as a scoping review employing Online Mendeliain Inheritance in Man, PubMed, and Cochrane to identify cases of BRA with known underlying genetic (chromosomal vs. single gene) etiologies and those described in syndromes without any known genetic etiology.

Use of cell salvage at the time of cesarean delivery: a meta-analysis of randomized controlled trials.

Objective: Excess blood loss from obstetrical hemorrhage requires transfusion of donor blood, a finite resource. Intraoperative cell salvage collects a patient's own blood that has been lost during cesarean delivery and returns it to their own circulation. We performed a meta-analysis to examine the perioperative outcomes in patients receiving cell salvage at the time of cesarean delivery.

Maternal outcomes of a cohort of pregnancies affected by non-immune hydrops fetalis.

Objective: To describe the maternal outcomes of a prospective cohort of non-immune hydrops fetalis (NIHF) pregnancies with negative standard-of-care evaluations.

Methods: This study was a secondary analysis of a prospective cohort study of NIHF pregnancies with negative work-ups (infection, alloimmune anemia, fetomaternal hemorrhage, and chromosomal disorders). Outcomes were obstetric complications, including pre-eclampsia, mirror syndrome, preterm birth, polyhydramnios, postpartum hemorrhage, and maternal mental health.

Misoprostol with balloon vs oxytocin with balloon in high-risk pregnancy induction: a randomized controlled trial.

Background: Pregnancies at high risk for maternal, fetal, or placental complications often necessitate induction of labor in the late preterm or early term period for delivery. Limited data exist on the safest method of induction to use in this specific patient population.

Objective: This study aimed to compare the combination of oxytocin plus a Cook balloon vs misoprostol plus a Cook balloon for induction of labor in high-risk pregnancies.

Imaging and outcomes of fetal adrenal hemorrhage: A systematic review.

Objective: To describe prenatal and postnatal imaging findings of fetal adrenal hemorrhage (FAH) and its associated perinatal outcomes, including frequency of postnatal surgical intervention.

Method: A systematic literature review of seven electronic databases was conducted from inception until January 2022, with 2008 articles identified reporting prenatally identified fetal adrenal masses. Studies with confirmed FAH diagnosis were included.

Management of a Retained Broken Suture Needle During Cerclage Placement.

Background: Broken suture needles with unintentional foreign body retention are an uncommon occurrence during obstetric procedures. Few reports exist in the literature of cases in pregnant patients. We report a case with the pregnancy management of a broken needle during cerclage placement that was retained in the cervix until repeat cesarean delivery.

Changes in Rates of Hypertensive Disorders of Pregnancy Among Nulliparous Patients After the ARRIVE (A Randomized Trial of Induction Versus Expectant Management) Trial.

The ARRIVE (A Randomized Trial of Induction Versus Expectant Management) trial demonstrated lower rates of hypertensive disorders of pregnancy (HDP) among low-risk nulliparous patients undergoing labor induction at 39 weeks of gestation. We conducted a population-based cohort study in which we evaluated the association between the routinization of 39-week induction and the rate of HDP by comparing rates before and after the ARRIVE trial publication, using the National Vital Statistics System. Logistic regression models were used to project what the HDP rate would have been based on trends seen pre-ARRIVE.

SARS-CoV-2 Covid-19 Infection During Pregnancy and Differential DNA Methylation in Human Cord Blood Cells From Term Neonates.

Background: The global pandemic of coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). About 18.4% of total Covid-19 cases were reported in children.

Connecting the dots: Carrier screening and the Genetic Information Nondiscrimination Act in the United States.

Objective: To highlight the possibility of genetic discrimination in the United States with respect to carrier screening under limitations of the Genetic Information Nondiscrimination Act (GINA) and to encourage providers to educate patients about this possibility during pretest counseling.

Methods: Review of current professional guidelines and practice resources regarding the necessary components of pretest counseling for carrier screening in the context of GINA's limitations and the potential impact of carrier screening results on life, long-term care and disability insurance.

Results: Current practice resources advise that patients in the United States should be informed that their employer or health insurance company generally cannot use their genetic information during the underwriting process.

Mirror syndrome: a systematic literature review.

Objective: This study aimed to review the diagnostic criteria for mirror syndrome and describe its clinical presentation.

Data Sources: Databases from PubMed, Scopus, Cochrane Library, ClinicalTrials.gov, and CINAHL were inquired for case series containing ≥2 cases of mirror syndrome from inception to February 2022.

HELLP syndrome at <23 weeks' gestation: a systematic literature review.

Objective: We performed a systematic review to evaluate the clinical presentation and maternal and fetal outcomes in pregnancies with early-onset HELLP (hemolysis, elevated liver enzymes, and low platelets) syndrome.

Data Sources: PubMed, Ovid MEDLINE, Scopus, CINAHL, Cochrane Library, and ClinicalTrials.gov were queried from inception through January 1, 2023 with the following terms: "HELLP syndrome," "HELLP," "hemolysis, elevated liver enzymes, low platelets," "hemolysis, elevated liver enzymes, low platelets syndrome," "pre-viable," "peri-viable," "previable," "periviable," "first trimester," "second trimester," "before 23 weeks," "<23 weeks," "<23 week gestation," and "before 23 weeks gestation.
