"Inpatient pharmacological thromboprophylaxis in the antepartum period: an argument for universal thromboprophylaxis".

Venous thromboembolism (VTE), a largely preventable condition, accounts for almost 15% of maternal mortalities. The physiologic changes of pregnancy, including quantitative changes in coagulation factors and compression of vasculature by the gravid uterus, cause an increase in risk of VTE, including deep vein thromboembolism (DVT), pulmonary embolism (PE), and stroke (CVA). Long term antepartum admission for preeclampsia, preterm prelabor rupture of membranes (PPROM) or other high-risk pregnancy needs present additional risk factors for VTE due to the patient's medical condition and their inpatient status.

Perinatal Outcomes Based on Number of Digital Exams in Patients with Preterm Prelabor Rupture of Membrane.

Objective:  The American College of Obstetricians and Gynecologists recommends speculum exams, rather than digital exams, for evaluation of the cervix after preterm prelabor rupture of membranes (PPROM). However, in clinical practice, digital exams may be necessary. We examined whether increasing numbers of digital exams were associated with adverse outcomes in PPROM.

Association between interpregnancy interval and the labor curve.

Background: Both short and long interpregnancy intervals are associated with adverse pregnancy outcomes; however, the impact of interpregnancy intervals on labor progression is unknown.

Objective: We examined the impact of interpregnancy intervals on the labor curve, hypothesizing that those with a longer interpregnancy intervals would have slower labor progression.

Study Design: This is a retrospective cohort study of patients with a history of one prior vaginal delivery admitted for induction of labor or spontaneous labor with a singleton gestation ≥37 weeks at an academic medical center between 2004 and 2015.

Severe perineal lacerations in induction of labor versus expectant management: A systematic review and meta-analysis of randomized controlled trials.

Objective: This study aimed to evaluate if induction of labor (IOL) is associated with an increased risk of severe perineal laceration.

Data Sources: A systematic search was conducted in MEDLINE, Ovid, Scopus, ClinicalTrials.gov, Cochrane Central Register of Controlled Trials, and CINHAL using a combination of keywords and text words related to "induction of labor," "severe perineal laceration," "third-degree laceration," "fourth-degree laceration," and "OASIS" from inception of each database until January 2023.

Intrapartum Oxygen for Fetal Resuscitation: State of the Science.

Purpose Of Review: This review aims to summarize the current evidence regarding maternal oxygen supplementation for Category II fetal heart tracings (FHT) in labor. We aim to evaluate the theoretical rationale for oxygen administration, the clinical efficacy of supplemental oxygen, and the potential risks.

Recent Findings: Maternal oxygen supplementation is an intrauterine resuscitation technique rooted in the theoretic rationale that hyperoxygenating the mother results in increased oxygen transfer to the fetus.

Suture type for hysterotomy closure: a systematic review and meta-analysis of randomized controlled trials.

Objective: Recent randomized controlled trials have demonstrated an association between uterine closure technique at the time of cesarean delivery and short- and long-term operative outcomes with varied results. This systematic review and meta-analysis aimed to examine types of suture material used for cesarean delivery.

Data Sources: Scopus, PubMed, Cochrane Central Register of Controlled Trials, Ovid, and ClinicalTrials.

Prophylactic rotation for malposition in the second stage of labor: a systematic review and meta-analysis of randomized controlled trials.

Objective: This study aimed to evaluate if manual rotation, undertaken during labor, of fetuses in occiput posterior or occiput transverse position led to an increased rate of spontaneous vaginal delivery.

Data Sources: Searches were performed in MEDLINE, Ovid, Scopus, ClinicalTrials.gov, and the Cochrane Central Register of Controlled Trials with the use of a combination of keywords and text words related to "occiput posterior," "occiput transverse," and "manual rotation" from inception of the databases to July 2021.

Evaluation of an Initiative to Decrease the Use of Oxygen Supplementation for Category II Fetal Heart Rate Tracings.

Objective: To examine compliance with a guideline to reduce exposure to supplemental oxygen for category II fetal heart rate (FHR) tracings in normally oxygenated laboring patients.

Methods: All patients in labor in an urban academic medical center from January 1 to July 31, 2020 were assessed. The preintervention group included those who delivered from January 1 to March 19, 2020.

Effect of intrapartum oxygen on the rate of cesarean delivery: a meta-analysis.

Objective: This study aimed to determine if maternal intrapartum administration of oxygen altered the rate of cesarean delivery compared with room air.

Data Sources: This study was a systematic review and meta-analysis of randomized controlled trials. Searches were performed in MEDLINE, OVID, Scopus, ClinicalTrials.

Blood type and postpartum hemorrhage by mode of delivery: A retrospective cohort study.

Objective: To assess the relationship between postpartum hemorrhage and ABO blood type for vaginal delivery and cesarean delivery.

Study Design: This is a retrospective cohort study of data abstracted from the PeriBank database regarding demographics and delivery outcomes. All live singleton deliveries from January 2011 until March 2018 were included in this study.

Pregnant women with severe or critical coronavirus disease 2019 have increased composite morbidity compared with nonpregnant matched controls.

Background: In March 2020, as community spread of severe acute respiratory syndrome coronavirus 2 became increasingly prevalent, pregnant women seemed to be equally susceptible to developing coronavirus disease 2019. Although the disease course usually appears mild, severe and critical cases of coronavirus disease 2019 seem to lead to substantial morbidity, including intensive care unit admission with prolonged hospital stay, intubation, mechanical ventilation, and even death. Although there are recent reports regarding the impact of coronavirus disease 2019 on pregnancy, there is a lack of information regarding the severity of coronavirus disease 2019 in pregnant vs nonpregnant women.

Clinical course of severe and critical coronavirus disease 2019 in hospitalized pregnancies: a United States cohort study.

Background: The coronavirus disease 2019 pandemic has had an impact on healthcare systems around the world with 3 million people contracting the disease and 208,000 cases resulting in death as of this writing. Information regarding coronavirus infection in pregnancy is still limited.

Objective: This study aimed to describe the clinical course of severe and critical coronavirus disease 2019 in hospitalized pregnant women with positive laboratory testing for severe acute respiratory syndrome coronavirus 2.
