Using ICD Codes Alone May Misclassify Overdoses Among Perinatal People.

Introduction: As perinatal drug overdoses continue to rise, reliable approaches are needed to monitor overdose trends during pregnancy and postpartum. This analysis aimed to determine the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of ICD-9/10-CM codes for drug overdose events among people in the MATernaL and Infant clinical NetworK (MAT-LINK) with medication for opioid use disorder (MOUD) during pregnancy.

Methods: People included in this analysis had electronic health record (EHR) documentation of MOUD and a known pregnancy outcome from January 1, 2014 through August 31, 2021.

Hepatitis C Virus Infection in Pregnant Individuals with Opioid Use Disorder and Its Association with Preterm Birth.

Objective:  Both hepatitis C virus (HCV) and opioid use disorder (OUD) have been associated with higher rates of preterm birth (PTB). It is unknown whether the higher prevalence of HCV in individuals with OUD may contribute to this association. The objective of this study is to evaluate the association between HCV and PTB in pregnant individuals with OUD.

Effect of an Intrapartum Pelvic Dilator Device on Levator Ani Muscle Avulsion During Primiparous Vaginal Delivery: A Pilot Randomized Controlled Trial.

Introduction And Hypothesis: The objective was to evaluate the safety and effectiveness of an intrapartum electromechanical pelvic floor dilator designed to reduce the risk of levator ani muscle (LAM) avulsion during vaginal delivery.

Methods: A multicenter, randomized controlled trial enrolled nulliparous participants planning vaginal delivery. During the first stage of labor, participants were randomized to receive the intravaginal device or standard-of-care labor management.

Outbreak of postpartum group a Streptococcus infections on a labor and delivery unit.

A healthcare-associated group A Streptococcus outbreak involving six patients, four healthcare workers, and one household contact occurred in the labor and delivery unit of an academic medical center. Isolates were highly related by whole genome sequencing. Infection prevention measures, healthcare worker screening, and chemoprophylaxis of those colonized halted further transmission.

Neurodevelopmental Outcomes After Late Preterm Antenatal Corticosteroids: The ALPS Follow-Up Study.

Importance: The Antenatal Late Preterm Steroids (ALPS) trial changed clinical practice in the United States by finding that antenatal betamethasone at 34 to 36 weeks decreased short-term neonatal respiratory morbidity. However, the trial also found increased risk of neonatal hypoglycemia after betamethasone. This follow-up study focused on long-term neurodevelopmental outcomes after late preterm steroids.

High-Dose Buprenorphine Initiation in the Management of Opioid Use Disorder in Pregnancy.

Buprenorphine is commonly used as a treatment for opioid use disorder (OUD). Transition to buprenorphine traditionally has been done using a low-dose initiation regimen due to concerns surrounding precipitated withdrawal. There are increasing data supporting use of a high-dose initiation regimen in the nonpregnant population.

Prolonged detection of urine norfentanyl in individuals enrolled in a medication for opioid use disorder in pregnancy and postpartum program: a case series.

Background: Although urine drug testing can have vast legal and social ramifications, its interpretation during pregnancy and after birth remains not well understood. Fentanyl metabolism is altered by an individual's genetics, history of opioid use, and liver function. However, little is known about the clearance of fentanyl or its primary metabolite, norfentanyl, in the peripartum period.

Use of non-invasive cardiac monitoring to guide discontinuation of postpartum magnesium sulfate in individuals with preeclampsia with severe features.

Objectives: To determine the utility of using total peripheral systemic vascular resistance assessed using non-invasive cardiac monitor for individualizing the duration of postpartum magnesium sulfate in individuals with preeclampsia with severe features.

Study Design: Single center pilot randomized controlled trial in which singleton pregnant individuals with preeclampsia with severe features were randomized to 24 h of postpartum magnesium sulfate per standard of care (control group) or individualized duration of postpartum magnesium sulfate based on reduction in post-delivery systemic vascular resistance (intervention group). Systemic vascular resistance was assessed with non-invasive cardiac monitoring using the Cheetah® system.

Association between Individual versus Community-level Social Vulnerability and Neonatal Opioid Withdrawal Syndrome among Pregnant Individuals Receiving Buprenorphine for Opioid Use Disorder.

Objective: Individual patient-level measures of adverse social determinants of health are associated with neonatal opioid withdrawal syndrome (NOWS), but the relative impact of community-level adverse social determinants of health remains to be defined. We examined the association between community-level social vulnerability and NOWS among pregnant individuals receiving buprenorphine for opioid use disorder.

Study Design: We conducted a secondary analysis of an established cohort of pregnant individuals and their infants participating in a multidisciplinary prenatal/addiction care program from 2013 to 2021.

Noninvasive Bioelectronic Treatment of Postcesarean Pain: A Randomized Clinical Trial.

Importance: Improved strategies are needed to decrease opioid use after cesarean delivery but still adequately control postoperative pain. Although transcutaneous electrical stimulation devices have proven effective for pain control after other surgical procedures, they have not been tested as part of a multimodal analgesic protocol after cesarean delivery, the most common surgical procedure in the United States.

Objective: To determine whether treatment with a noninvasive high-frequency electrical stimulation device decreases opioid use and pain after cesarean delivery.

Postpartum Hepatitis C Linkage to Care Program in a Co-located Substance Use Disorders Treatment Model.

Purpose: Hepatitis C virus (HCV) is increasingly prevalent in pregnancy and among people with substance use disorders (SUD). Highly effective treatments are now available for chronic HCV. Qualifying for HCV treatment often requires preauthorization and several clinical criteria, including laboratory assessment of liver function and other infectious diseases and liver imaging to assess for fibrosis.

Real-World Utilization of an Intrauterine, Vacuum-Induced, Hemorrhage-Control Device.

Objective: To assess the real-world effectiveness and safety of a U.S. Food and Drug Administration (FDA)-cleared intrauterine vacuum-induced-hemorrhage control device for postpartum hemorrhage (PPH) management.

Increasing rates of sars-cov-2 infection in newborns during the omicron variant epoch.

Problem: Transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from infected pregnant individuals to the fetus or newborn occurs from 1.2% to 4.3%.

Interventions of Postpartum Hemorrhage.

Postpartum hemorrhage is a common and potentially life-threatening obstetric complication, with successful management relying heavily on early identification of hemorrhage and prompt intervention. This article will review the management of postpartum hemorrhage, including initial steps, exam-specific interventions, medical therapy, minimally invasive, and surgical interventions.

Maternal Coagulation Disorders and Postpartum Hemorrhage.

Coagulation disorders are rare causes of postpartum hemorrhage. Disturbances in coagulation should be suspected in patients with a family history of coagulopathy, those with a personal history of heavy menstrual bleeding, and those with persistent bleeding despite correction of other causes. The coagulopathic conditions discussed include disseminated intravascular coagulation, platelet disorders, and disturbances of coagulation factors.

Group-based medical mistrust and care expectations among black patients seeking addiction treatment.

Background: Black patients seeking addiction care experience poorer treatment access, retention, and outcomes when compared to White counterparts. Black patients may have elevated group-based medical mistrust, which has been associated with poorer health outcomes and increased experiences of racism across multiple healthcare contexts. The relationship between group-based medical mistrust and expectations for addiction treatment among Black individuals remains untested.

Aspirin and Pravastatin for Preeclampsia Prevention in High-Risk Pregnancy.

Preeclampsia is a hypertensive disorder of pregnancy affecting up to 8% of pregnancies. It is associated with significant neonatal and maternal morbidities and mortality. Although its pathogenesis is not completely understood, abnormal placentation resulting in imbalance in angiogenic factors, increased inflammation, and endothelial dysfunction are thought to be key pathways in the development of the disease.

Comparison of neonatal outcomes in pregnant women undergoing medication-assisted treatment of opioid use disorder with methadone or buprenorphine/naloxone.

Introduction: The number of pregnant women with opioid use disorder (OUD) has quadrupled from 1999 to 2014. Current first line treatment for OUD in pregnancy is methadone with increasing support for buprenorphine. Limited data exist on use of buprenorphine/naloxone for OUD in pregnancy despite it being standard therapy in the non-pregnant individuals.

Fetal Autopsy Rates in the United States: Analysis of National Vital Statistics.

Objective: To identify rates of fetal autopsy in the United States as well as demographic and clinical characteristics related to consent to autopsy after stillbirth.

Methods: This is a population-based retrospective cohort study using U.S.

Trial of Intrapartum Extended-Release Nifedipine to Prevent Severe Hypertension Among Pregnant Individuals With Preeclampsia With Severe Features.

Background: Preeclampsia is associated with maternal and perinatal morbidity. Besides acute therapy for severe hypertension, best practices are lacking for intrapartum hypertension management. Our objective was to test the hypothesis that intrapartum initiation of extended-release nifedipine in individuals with preeclampsia with severe features prevents severe hypertension.

Association between social vulnerability and COVID-19 vaccination hesitancy and vaccination in pregnant and postpartum individuals.

Objective: To evaluate the association of community-level social vulnerability with COVID-19 vaccine hesitancy and vaccination among pregnant and postpartum individuals.

Methods: Prospective cohort study assessing COVID-19 vaccine hesitancy among pregnant and postpartum individuals. We performed a baseline survey on COVID-19 vaccine hesitancy from 03/22/21 to 04/02/21, and a follow-up survey on COVD-19 vaccination status 3- to 6-months later.
