Neonatal Outcomes Are Similar between Patients with Resolved and Those with Persistent Oligohydramnios.

Objective: Oligohydramnios (defined as amniotic fluid volume < 5 cm or deepest vertical pocket < 2 cm) is regarded as an ominous finding on prenatal ultrasound. Amniotic fluid, however, is not static, and to date, there have been no studies comparing perinatal outcomes in patients who are diagnosed with oligohydramnios that resolves and those who have persistent oligohydramnios.

Study Design: This is a secondary analysis of a National Institutes of Health-funded retrospective cohort study of singleton gestations delivered at a tertiary care hospital between 2002 and 2013 with mild hypertensive disorders and/or fetal growth restriction (FGR).

Utility of Repeat Uterine Cavity Evaluation in the Infertility Workup.

Uterine cavity abnormalities contribute to infertility. The purpose of this study was to evaluate the incidence, recurrence rates, and risk factors for uterine cavity abnormalities in women undergoing infertility workup and treatment, focusing on the utility of routinely repeated imaging. Retrospective cohort study at single academic medical center of 833 infertile women who had uterine cavity evaluations performed at least 9 months apart.

From "disappointing" to "fantastic": Women's experiences with labor induction in a U.S. tertiary hospital.

Objective: The series of interventions that comprise labor induction shape patient experiences; however, patient perceptions are not always considered when structuring the process of care. Through qualitative interviews, we elucidated women's expectations and experiences regarding labor induction.

Methods: Labor induction patients were recruited from a United States tertiary care hospital's postpartum mother-baby unit and invited to participate in semi-structured qualitative interviews.

Predicting primary cesarean delivery in pregnancies complicated by gestational diabetes mellitus.

Background: Prediction models have shown promise in helping clinicians and patients engage in shared decision-making by providing quantitative estimates of individual risk of important clinical outcomes. Gestational diabetes mellitus is a common complication of pregnancy, which places patients at higher risk of primary CD. Suspected fetal macrosomia diagnosed on prenatal ultrasound is a well-known risk factor for primary CD in patients with gestational diabetes mellitus, but tools incorporating multiple risk factors to provide more accurate CD risk are lacking.

Televisits Compared With In-Person Visits for Routine Antenatal Care: A Systematic Review.

Objective: To compare benefits and harms of televisits and in-person visits in people receiving routine antenatal care.

Data Sources: A search was conducted of PubMed, Cochrane databases, EMBASE, CINAHL, and ClinicalTrials.gov through February 12, 2022, for antenatal (prenatal) care, pregnancy, obstetrics, telemedicine, remote care, smartphones, telemonitoring, and related terms, as well as primary study designs.

Reduced Compared With Traditional Schedules for Routine Antenatal Visits: A Systematic Review.

Objective: To assess differences in maternal and child outcomes in studies comparing reduced routine antenatal visit schedules with traditional schedules.

Data Sources: A search was conducted of PubMed, Cochrane databases, EMBASE, CINAHL, and ClinicalTrials.gov through February 12, 2022, searching for antenatal (prenatal) care, pregnancy, obstetrics, telemedicine, remote care, smartphones, telemonitoring, and related terms, as well as primary study designs.

Outcomes among Neonates after a Diagnosis of Persistent or Transient Fetal Growth Restriction Delivered at Term.

Objective: This study aimed to evaluate whether transient fetal growth restriction (FGR) that resolves prior to delivery confers a similar risk of neonatal morbidity as uncomplicated FGR that persists at term.

Study Design: This is a secondary analysis of a medical record abstraction study of singleton live-born pregnancies delivered at a tertiary care center between 2002 and 2013. Patients with fetuses that had either persistent or transient FGR and delivered at 38 weeks or later were included.

Changes to Prenatal Care Visit Frequency and Telehealth: A Systematic Review of Qualitative Evidence.

Objective: To systematically review patient, partner or family, and clinician perspectives, preferences, and experiences related to prenatal care visit schedules and televisits for routine prenatal care.

Data Sources: PubMed, the Cochrane databases, EMBASE, CINAHL, ClinicalTrials.gov , PsycINFO, and SocINDEX from inception through February 12, 2022.

Frailty as a predictor of delayed initiation of adjuvant chemotherapy in patients with ovarian cancer.

Objective: This study aimed to identify whether frailty is associated with the time between surgery and the initiation of chemotherapy for patients with ovarian cancer.

Methods: This retrospective cohort study included patients 18 years or older with stage II to IV ovarian cancer who underwent primary debulking surgery at a tertiary medical center between July 2006 and July 2015. Basic demographics and clinical information were obtained from a departmental database and the electronic medical record.

Risk factors for respiratory distress syndrome among high-risk early-term and full-term deliveries.

Objective: To identify whether risk factors for respiratory distress syndrome (RDS) differ between early-term and full-term births.

Study Design: This is a secondary analysis of a large NIH-funded retrospective cohort study including patients who delivered at a tertiary-care obstetric hospital between January 2002 and March 2013 with comorbid diabetes, hypertensive disorders, and/or fetal growth restriction (FGR). Pregnancies complicated by severe preeclampsia and multifetal gestations were excluded.

Analysis of Gestational Weight Gain During the COVID-19 Pandemic in the US.

This cross-sectional study assesses changes in gestational weight gain in individuals giving birth to live infants during the COVID-19 pandemic.

Development and Internal Validation of a Risk Prediction Model for Acute Cardiovascular Morbidity in Preeclampsia.

Background: Women with preeclampsia are at increased short-term risk of adverse cardiovascular outcomes during pregnancy and the early postpartum period. We aimed to develop and internally validate a risk assessment tool to predict acute cardiovascular morbidity in preeclampsia.

Methods: The study was conducted at an academic obstetrics hospital.

Health Outcomes Associated With Clinician-initiated Delivery for Hypertensive Disorders at 34-38 Weeks' Gestation.

Background: Clinicians caring for the nearly 10% of patients in the United States with nonsevere hypertensive disorders in late pregnancy need better evidence to balance risks and benefits of clinician-initiated delivery.

Methods: We conducted a record-based cohort study of maternal and infant health outcomes among deliveries from 2002-2013 at Women & Infants Hospital of Rhode Island. Participants had gestational hypertension or nonsevere preeclampsia before 39 weeks' gestation (N=4,295).

Prediction Model Assessing Risk of Delivery after Diagnosis of Abnormal Umbilical Artery Doppler.

Objective: Umbilical artery Doppler (UAD) velocimetry abnormalities are associated with increased neonatal morbidity and mortality. Currently, there are no risk stratification methods to assist in antepartum management such as timing of antenatal corticosteroids (ACS). Therefore, we sought to develop a model to predict risk of delivery within 7 days following diagnosis of abnormal UAD velocimetry in patients with fetal growth restriction (FGR).

The independent and combined influences of small for gestational age and socioeconomic status on newborn metabolite levels.

Objectives: To determine whether socioeconomic status (SES) and small birthweight for gestational age (SGA) exhibit independent or joint effects on infant levels of 42 metabolites.

Study Design: Population-based retrospective cohort of metabolic newborn screening information linked to hospital discharge data. SGA infants defined by birthweight <10th percentile for gestational age by sex.

Outpatient Opioid Use After Cesarean Delivery.

Objectives: With a goal of informing opioid prescribing after cesarean delivery, we compared inpatient, prescribed, and outpatient Morphine Equivalent Doses (MED) and patient characteristics.

Methods: Patients were enrolled after cesarean delivery and followed for 2-5 weeks with demographic, opioid use, and clinical characteristics collected from participants and the medical record. T-test, ANOVA, linear regression, and Pearson correlation coefficients were used in analyses.

Term Labor Induction and Cesarean Delivery Risk among Obese Women with and without Comorbidities.

Objective: Findings of the recent ARRIVE (A Randomized Trial of Induction Versus Expectant Management) trial, showing reduced cesarean risk with elective labor induction among low-risk nulliparous women at 39 weeks' gestation, have the potential to change interventional delivery practices but require examination in wider populations. The aim of this study was to identify whether term induction of labor was associated with reduced cesarean delivery risk among women with obesity, evaluating several maternal characteristics associated with obesity, induction, and cesarean risk.

Study Design: We studied administrative records for 66,280 singleton, term births to women with a body mass index ≥30, without a prior cesarean delivery, in New York City from 2008 to 2013.

Prediction Model for Vaginal Birth After Induction of Labor in Women With Hypertensive Disorders of Pregnancy.

Objective: To identify characteristics associated with vaginal delivery compared with cesarean delivery after labor induction among women with hypertensive disorders of pregnancy and to develop and validate a prediction model to assist in clinical care.

Methods: We studied a retrospective cohort of women with singleton pregnancies who had hypertensive disorders of pregnancy and who underwent induction of labor at 34 weeks of gestation or more from January 1, 2002, to March 31, 2013. Exclusion criteria included spontaneous labor, prelabor cesarean delivery, and known fetal anomalies.
