No abstract text is available yet for this article.

BACKGROUND: Opioid use disorder (OUD) among pregnant individuals in the U.S. has been on the rise, and carries significant health risks if left untreated. Despite the effectiveness of medication for opioid use disorder (MOUD), rates of treatment utilization remain low, and access varies by state. This study seeks to expand on what is known about the utilization of MOUD by estimating annual percentages of MOUD use among treatment admissions among pregnant individuals across all 50 states and U...

The opioid epidemic in the United States has led to an increasing number of pregnant patients with opioid use disorder (OUD) presenting to obstetric units. Caring for this complex patient population requires an interdisciplinary approach involving obstetricians, anesthesiologists, addiction medicine physicians, psychiatrists, and social workers. The management of acute pain in the parturient with OUD can be challenging due to several factors, including respiratory depression, opioid tolerance, and opioid-induced hyperalgesia...

BACKGROUND AND AIMS: Identifying effective opioid treatment options during pregnancy is a high priority due to the growing prevalence of opioid use disorder across North America. We assessed the temporal impact of three population-level interventions on the use of opioid agonist treatment (OAT) during pregnancy in Ontario, Canada. DESIGN: This was a population-based time-series analysis to identify trends in the monthly prevalence of pregnant people dispensed methadone and buprenorphine...

AIM: How maternal opioid maintenance treatment (OMT) affects children is under-researched. This population-based registry study investigated child growth and somatic health following intrauterine exposure to this treatment. METHODS: Children born between 1 March 2011 and 30 May 2021 to mothers who used buprenorphine, buprenorphine-naloxone, or methadone throughout their pregnancies were followed for 2 years at the Helsinki University Hospital, Finland. Appropriate statistical tests were used to compare the treatment groups...

Weekly and monthly CAM2038 (Brixadi® ) extended-release subcutaneous buprenorphine (XR bup) has been available in Europe and Australia for several years and was approved by the Food and Drug Administration in May 2023. Little is known about the clinical experience of patients and providers using this new medication during prenatal care. Two cases of pregnant persons with opioid use disorder receiving weekly XR bup in an ongoing randomized multi-site outpatient clinical trial are presented along with a brief review of the pharmacology and literature on XR bup formulations...

BACKGROUND: Treatment-seeking people with opioid use disorder (OUD) who are capable of pregnancy need accurate information about the potential impact of medication to treat OUD (MOUD) on fertility to make informed choices about treatment that are consistent with their reproductive wishes. There is a dearth of research on fertility associated with MOUD receipt in birthing people with OUD. OBJECTIVE: To estimate the association between treatment with MOUD and odds of conception among birthing people using national administrative claims...

OBJECTIVE: Differences in infant health outcomes by maternal opioid use disorder (OUD) status is understudied. We measured the association between maternal OUD during pregnancy and infant mortality and investigated whether these associations differ by infant neonatal opioid withdrawal syndrome (NOWS) or maternal receipt of medication for OUD (MOUD) during pregnancy. METHODS: We sampled 204,543 Medicaid-paid births from Wisconsin, United States (2010-2018). The primary exposure was any maternal OUD during pregnancy...

OBJECTIVES: While pregnancy presents a strong motivation to seek and comply with Opioid Use Disorder (OUD) treatment, the risk for relapse during the postpartum period is high. The purpose of the present study was to examine the impact of babywearing while admitted to the NICU on urges to use substances within 9 months of childbirth. METHODS: Mothers with a history of OUD ( N  = 47, M age = 28.91, SD  = 5.14; 48.9% White, 19.1% Latinx) and their newborns were randomly assigned to the intervention (babywearing) or control (infant rocker) condition while admitted to a NICU...

INTRODUCTION: In bipolar women who took lithium during pregnancy, several epidemiology studies have reported small increases in a rare fetal cardiac defect termed Ebstein's anomaly. METHODS: Behavioral, environmental, and lifestyle-associated risk factors associated with bipolar disorder and health insurance status were determined from an Internet search. The search was conducted from October 1, 2023, through October 14, 2023. The search terms employed included the following: bipolar, bipolar disorder, mood disorders, pregnancy, congenital heart defects, Ebstein's anomaly, diabetes, hypertension, Medicaid, Medicaid patients, alcohol use, cigarette smoking, marijuana, cocaine, methamphetamine, narcotics, nutrition, diet, obesity, body mass index, environment, environmental exposures, poverty, socioeconomic status, divorce, unemployment, and income...

BACKGROUND: Amid rising rates of neonatal opioid withdrawal syndrome (NOWS) worldwide and in many regions of the USA, we conducted an audit study ("secret shopper study") to evaluate the influence of county-level buprenorphine capacity and rurality on county-level NOWS rates. METHODS: In 2019, up to three phone calls were made to buprenorphine prescribers in the state of Missouri (USA). County-level buprenorphine capacity was defined as the number of clinicians (across all specialties) accepting pregnant people divided by the number of births...

Pregnancy can be a time of joy and hope but, for birthing parents struggling with a substance use disorder (SUD), it can be challenging. Social stigma, shame, and the potential legal ramifications present barriers to individuals seeking the care they need. Marginalized groups, in particular, face challenges that put them at even greater risk for substance misuse. Substance use during pregnancy can further impair the individual's level of functioning, and it has also been associated with problems in the social, emotional, and cognitive development of their children...

Background  Conventional buprenorphine inductions require patients to abstain from full agonist opioids until they experience mild-to-moderate opioid withdrawal. We described a successful buprenorphine induction case in a pregnant patient using microdosing, which avoided withdrawal symptoms. Case Presentation  The patient is a 29-year-old G2P1001 at 18 2/7 weeks of gestation, who desired a switch from methadone to buprenorphine to minimize neonatal opioid withdrawal syndrome (NOWS), which complicated her last pregnancy...

BACKGROUND: Maternal opioid use (MOU) remains a public health concern. Studies have demonstrated significant increases in MOU, but estimates using ICD-10-CM or stratified by sociodemographic variables are limited. OBJECTIVES: Using a statewide, population-based dataset of Florida resident deliveries from 2000 to 2019, we examined the trend of MOU by age, race/ethnicity, education level, and insurance. METHODS: Florida administrative data was used to conduct a retrospective cohort study...

BACKGROUND: Opioid use disorder (OUD) during pregnancy is associated with high mortality rates and neonatal opioid withdrawal syndrome (NOWS). Buprenorphine, an opioid, is used to treat OUD and NOWS. Buprenorphine active metabolite (norbuprenorphine) can cross the placenta and cause neonatal respiratory depression (EC50 = 35 ng/mL) at high brain extracellular fluid (bECF) levels. Neonatal therapeutic drug monitoring using saliva decreases the likelihood of distress and infections associated with frequent blood sampling...

BACKGROUND: Women face unique barriers when seeking treatment for substance use disorders, often related to pregnancy and parenting. OBJECTIVES: This study adds to the extant literature by elucidating the pregnancy- and parenting-related barriers women face when initiating or continuing medication for opioid use disorder, specifically. DESIGN: This study is based on qualitative semi-structured interviews. METHODS: Three subgroups participated in semi-structured interviews regarding their experiences (N = 42): women with current or past opioid use disorders who have used or were presently using medication for opioid use disorder, professionals working in substance use disorder treatment programs, and criminal justice professionals...

OBJECTIVE: There is a lack of knowledge about the relative safety and efficacy of naltrexone for the treatment of pregnant individuals with opioid and/or alcohol use disorder, including the range of outcomes, in both the pregnant individual and the infant, over the course of peripartum period. Our objective was to describe these outcomes in a cohort of pregnant individuals on naltrexone. METHODS: In this prospective case series, 7 pregnant individuals with opioid use disorder (OUD) or alcohol use disorder (AUD) treated with naltrexone were followed from pregnancy through 12 months after delivery...

IMPORTANCE: Opioid exposure during pregnancy has been associated with preterm birth, but prior studies have not differentiated between spontaneous and indicated preterm birth or fully investigated these associations as functions of opioid dose. OBJECTIVE: To determine whether prescription opioid use during pregnancy is associated with spontaneous preterm birth and whether the association is dose-dependent. DESIGN, SETTING, AND PARTICIPANTS: This case-control study examined a retrospective cohort of pregnant patients enrolled in Tennessee Medicaid...

INTRODUCTION AND IMPORTANCE: Peripartum cardiomyopathy is an uncommon form of cardiomyopathy that develops in the latter stages of pregnancy or in the first few weeks following delivery. Anaesthetic management of caesarean section of a parturient with dilated cardiomyopathy is challenging due to its nature of impaired ventricular contractility coupled with cardiovascular changes during pregnancy. This is significantly worse in a resource-constrained environment with restricted access to medications and equipment...

BACKGROUND: Risk of fatal drug overdose is higher in pregnant and postpartum people with substance use disorder (SUD) than for nonpregnant women of reproductive age. It is recommended that naloxone is prescribed for pregnancies complicated by opioid or stimulant use disorder. OBJECTIVE: The purpose of this study was to assess the rates of naloxone coprescribing with buprenorphine in a perinatal SUD (PSUD) specialty clinic and identify opportunities for pharmacist-led interventions to improve communication and documentation surrounding naloxone access to achieve a rate of 100% coprescribing of naloxone with buprenorphine...
