[PMID: 35906283 DOI: 10.1038/s41372-022-01466-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/12/2022] [Revised: 06/23/2022] [Accepted: 07/12/2022] [Indexed: 11/09/2022]
Abstract
Prenatal opioid exposure has recently risen four-fold with limited data on the developmental effects on neonatal physiology. The objective of this systematic review is to develop an association between prenatal opioid exposure and fetal and neonatal cardiac and autonomic development and function. The review was conducted in accordance with PRISMA Guidelines, and searches were conducted using PubMed, Embase, CINAHL, and Web of Science between May 25 and October 27, 2020. Twenty studies fit inclusion criteria, in four categories: (1) fetal cardiac outcomes, (2) neonatal cardiac outcomes, (3) noninvasive autonomic outcomes, and (4) clinical and behavioral measures. For the meta-analysis, three studies (total of 210 subjects) were included. Effect sizes were measured as the mean difference in fetal heart rate between opioid-exposed and non-exposed groups. Mothers with prenatal opioid use had a significantly lower fetal heart rate as compared to mothers without prenatal opioid use, requiring further studies to determine clinical significance.

Prenatal opioid-exposed infant extracellular miRNA signature obtained at birth predicts severity of neonatal opioid withdrawal syndrome. Sci Rep 2022; 12:5941.

Abstract
Prenatal opioid exposure (POE) is commonly associated with neonatal opioid withdrawal syndrome (NOWS), which is characterized by a broad variability in symptoms and severity. Currently there are no diagnostic tools to reliably predict which infants will develop severe NOWS, while risk stratification would allow for proactive decisions about appropriate clinical monitoring and interventions. The aim of this prospective cohort study was to assess if extracellular microRNAs (miRNAs) in umbilical cord plasma of infants with POE could predict NOWS severity. Participants (n = 58) consisted of pregnant women receiving medications for opioid use disorder and their infants. NOWS severity was operationalized as the need for pharmacologic treatment and prolonged hospitalization (≥ 14 days). Cord blood miRNAs were assessed using semi-quantitative qRT-PCR arrays. Receiver operating characteristic curves and area under the curve (AUC) were estimated. The expression of three miRNAs (miR-128-3p, miR-30c-5p, miR-421) predicted need for pharmacologic treatment (AUC: 0.85) and prolonged hospitalization (AUC: 0.90). Predictive validity improved after two miRNAs (let-7d-5p, miR-584-5p) were added to the need for pharmacologic treatment model (AUC: 0.94) and another two miRNAs (let-7b-5p, miR-10-5p) to the prolonged hospitalization model (AUC: 0.99). Infant cord blood extracellular miRNAs can proactively identify opioid-exposed neonates at high-risk for developing severe NOWS.

Abstract
As the opioid epidemic escalates in westernized countries around the world, chronic opioid use during pregnancy has become a growing public health issue. There are increasing concerns that chronic maternal opioid use might adversely affect the developing fetal brain. Furthermore, the sudden discontinuation of the trans-placental opioid supply at birth puts newborns at acute risk for neonatal opioid withdrawal syndrome (NOWS). NOWS is a multi-system disorder that has been identified in approximately 50-80% of neonates exposed to opioids due to chronic maternal use. Clinically, NOWS affects the central and autonomic nervous systems as well as the gastrointestinal and respiratory tracts. The clinical features of NOWS include hyperirritability, high-pitched crying, restlessness, tremors, poor sleep, agitation, seizures, sweating, fever, poor feeding, regurgitation, diarrhea, and tachypnea. NOWS is currently diagnosed using a clinical scoring tool followed by toxicological confirmation of the presence of opioids in meconium or tissue specimens. The first-line treatments for NOWS are non-pharmacologic comfort measures. If these measures fail, neonates may be treated with opioids and/or sedatives. Since the severity of NOWS can be highly variable, it is quite difficult to predict which opioid-exposed neonates will require pharmacotherapy and prolonged hospitalization. Factors associated with maternal polysubstance use, including the use of illicit substances and tobacco, have been associated with the increased severity and duration of NOWS. Since neonates with NOWS are at increased risk for long-term adverse neurodevelopmental outcomes, ongoing monitoring beyond the neonatal period is essential.

Abstract
Purpose: The rising issue of opioid use during pregnancy poses an increased risk of fetal exposure to opioids in-utero and the development of neonatal abstinence syndrome (NAS). The cessation of exposure to opioids upon birth causes elevated levels of norepinephrine in the circulation enhancing sympathetic arousal. Skin conductance (SC) detects sympathetic-mediated sweating while the Neonatal Facial Coding System (NFCS) depicts facial expressions of stress and pain. We hypothesize that there will be a direct correlation between SC and NFCS scores, such that neonates with prenatal opioid exposure will have higher SC and facial responses to pain/stress as compared with healthy neonates without prenatal opioid exposure.Objective: This study evaluates the utility of SC and the NFCS in the objective assessment of early postnatal pain response in opioid-exposed and non-opioid exposed neonates.Methods: This prospective, single-center, pilot study enrolled opioid-exposed term neonates (>37 weeks) and healthy controls. Subjects were observed within 24-48 hours post-birth (and prior to opioid withdrawal) for pain at baseline, during, and post-heel lance/squeeze (HLS) with simultaneously measured SC and videotaped facial expressions. SC data included electro-dermal responses over time (EDR/second) and the average amplitude of responses (mean of peaks [MP]). Video data were scored using the NFCS by two trained coders with inter-rater agreement >85%.Results: SC and NFCS scores were significantly associated with both groups. The opioid-exposed neonates had significantly higher skin conductance indices, EDR/sec for the HLS phase, and MP for HLS and post phases as compared with controls (p < .05). Opioid-exposed neonates demonstrated higher NFCS at baseline (p = .003).Conclusions: Prenatal opioid exposure was associated with heightened sympathetic arousal during both pain and recovery phases and higher facial expressions of pain/distress at baseline only. A multimodal system of assessment may be useful in understanding the complexity and severity of opioid withdrawal associated with NAS.

Abstract
Opioid use disorders and the prescription of long-acting medications for their treatment have increased dramatically over the last decade among pregnant women. Newborns who experience prolonged in utero opioid exposure may develop neonatal abstinence syndrome (NAS). Until recently, much of the focus on improving care for NAS has been on pharmacologically-based care models. Recent studies have illustrated the benefits of rooming-in and parental presence on NAS outcomes. Single center Quality Improvement (QI) initiatives demonstrate the benefits of non-pharmacologic care bundles and symptom prioritization in decreasing the proportion of infants pharmacologically treated and length of hospital stay. Little remains known about the impact of these varied cared models on maternal-infant attachment and mental health. In this review article, we will propose an optimal model of care to improve short- and long-term outcomes for newborns, their mothers and families, and perinatal care systems.

Abstract
Neonates exposed prenatally to opioids will often develop a collection of withdrawal signs known as neonatal abstinence syndrome (NAS). The incidence of NAS has substantially increased in recent years placing an increasing burden on the healthcare system. Traditional approaches to assessment and management have relied on symptom-based scoring tools and utilization of slowly decreasing doses of medication, though newer models of care focused on non-pharmacologic interventions and rooming-in have demonstrated promise in reducing length of hospital stay and medication usage. Data on long-term outcomes for both traditional and newer approaches to care of infants with NAS is limited and an important area of future research. This review will examine the history, incidence and pathophysiology of NAS. We will also review diagnostic screening approaches, scoring tools, differing management approaches and conclude with recommendations for continued work to improve the care of infants with NAS.

Abstract
Infants with in-utero opioid exposure are most commonly assessed using the Finnegan Neonatal Abstinence Scoring System (FNASS) or a modified version of that tool. Traditionally, the purpose of these tools has been to characterize the extent of withdrawal signs to guide the pharmacologic treatment for infants with neonatal opioid withdrawal syndrome (NOWS). In the past decade however, in response to some of the limitations of the FNASS tool, there has been an increasing emphasis on developing novel assessment tools not based on the FNASS in addition to the promotion of non-pharmacologic treatment options as the first line treatment for infants with opioid exposure. Additionally, several prediction tools that may be useful in determining which patients are at high or low risk for receiving pharmacologic therapy have been developed. In this review, we will evaluate the clinical utility of these novel tools and will consider new avenues for future research.
