Abstract
This retrospective cohort study included 77 mother-infant dyads that delivered term pregnancies at a single tertiary care institution. The primary objective was to investigate whether maternal dose of opioid maintenance therapy during pregnancy affects infant outcomes. All infants had prenatal exposure to opioid maintenance therapies. Maternal dose was converted into morphine milligram equivalents (MMEs) and stratified into high- (MME >1000 mg) and low-dose groups (MME ≤1000 mg). Associations between infant outcomes and MME dosage were examined using Wilcoxon rank-sum and Fisher's Exact tests. Days to symptom control were significantly higher in the high MME group (5 days vs 2.8 days, P = .016). Rates of developmental delay at 24 months were higher in the high MME group (21.2% vs 4.5%, P = .0335). Maternal MME did not predict need for NOWS treatment. Higher MME-exposed infants should have optimized nonpharmacologic interventions for consolation and be increasingly observed for signs of developmental delay.

Characteristics of Factors Influencing the Occurrence of Cleft Lip and/or Palate: A Case Analysis and Literature Review. CHILDREN (BASEL, SWITZERLAND) 2024; 11:399. [PMID: 38671616 PMCID: PMC11049449 DOI: 10.3390/children11040399] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/11/2024] [Revised: 03/02/2024] [Accepted: 03/15/2024] [Indexed: 04/28/2024]
Abstract
INTRODUCTION Cleft lip with or without cleft palate (CL/P) stands as the most common congenital facial anomaly, stemming from multifactorial causes. OBJECTIVE Our study aimed to ascertain the prevalence and characteristics of cleft palates, identify associated risk factors to inform prevention and prenatal detection for early intervention, and assess postoperative rehabilitation protocols for cleft palates. DESIGN This study employs a retrospective descriptive and clinical approach. PATIENTS The study includes 103 children with cleft palates treated at the Department of Head and Neck Surgery Clinic for Children and Young Adults, Department of Clinical Pediatrics, University of Warmia and Mazury. METHODS We conducted a thorough evaluation of records, considering variables such as sex, cleft type, maternal occupation, parental education, and family history of clefts. Data analysis was carried out using R software version GPL-3 and ordinal logistic regression analyses. RESULTS Notably, children born to mothers who experienced significant stress during pregnancy exhibited a 9.4-fold increase in the odds of having bilateral cleft palates. Conversely, no substantial evidence was found to support the influence of the child's sex, birth order, body mass, maternal exposure to workplace toxins, infections, or drug toxicity on the dependent variable. CONCLUSIONS Our findings suggest that children with parents who have a history of clefts and those with less educated mothers are more likely to develop bilateral cleft palates. Additionally, children born to mothers experiencing stress during pregnancy face an increased risk of bilateral cleft palates. It is important to note that there is a paucity of literature on rehabilitation following various cleft palate surgical techniques in children.

Abstract
This study explores natural direct and joint natural indirect effects (JNIE) of prenatal opioid exposure on neurodevelopmental disorders (NDDs) in children mediated through pregnancy complications, major and minor congenital malformations, and adverse neonatal outcomes, using Medicaid claims linked to vital statistics in Rhode Island, United States, 2008-2018. A Bayesian mediation analysis with elastic net shrinkage prior was developed to estimate mean time to NDD diagnosis ratio using posterior mean and 95% credible intervals (CrIs) from Markov chain Monte Carlo algorithms. Simulation studies showed desirable model performance. Of 11,176 eligible pregnancies, 332 had ≥2 dispensations of prescription opioids anytime during pregnancy, including 200 (1.8%) having ≥1 dispensation in the first trimester (T1), 169 (1.5%) in the second (T2), and 153 (1.4%) in the third (T3). A significant JNIE of opioid exposure was observed in each trimester (T1, JNIE = 0.97, 95% CrI: 0.95, 0.99; T2, JNIE = 0.97, 95% CrI: 0.95, 0.99; T3, JNIE = 0.96, 95% CrI: 0.94, 0.99). The proportion of JNIE in each trimester was 17.9% (T1), 22.4% (T2), and 56.3% (T3). In conclusion, adverse pregnancy and birth outcomes jointly mediated the association between prenatal opioid exposure and accelerated time to NDD diagnosis. The proportion of JNIE increased as the timing of opioid exposure approached delivery.

Abstract
A peripheral injury drives neuroimmune interactions at the level of the injury and throughout the neuraxis. Understanding these systems will be beneficial in the pursuit to target persistent pain that involves both neural and immune components. In this review, we discuss the impact of injury on the development of neuroimmune signaling, along with data that suggest a possible cellular immune memory. We also discuss the parallel effects of injury in the nervous system and immune related areas including bone marrow, lymph node and central nervous system-related cells. Finally, we relate these findings to patient populations and current research that evaluates human tissue.

Abstract
OBJECTIVE The objective of this study is to investigate the effects of maternal perinatal depression symptoms and infant treatment status for neonatal abstinence syndrome (NAS) on maternal perceptions of infant regulatory behavior at 6 weeks of age. METHODS Mothers and their infants (N = 106; 53 dyads) were recruited from a rural, White cohort in Northeast Maine. Mothers in medication-assisted treatment (methadone) and their infants (n = 35 dyads) were divided based on the infant's NAS pharmacological treatment (n = 20, NAS+ group; n = 15, NAS- group) and compared with a demographically similar, nonexposed comparison group (n = 18 dyads; COMP group). At 6 weeks postpartum, mothers reported their depression symptoms Beck Depression Inventory-2nd Edition) and infant regulatory behaviors [Mother and Baby Scales (MABS)]. Infant neurobehavior was assessed during the same visit using the Neonatal Network Neurobehavioral Scale (NNNS). RESULTS Mothers in the NAS+ group showed significantly higher depression scores than the COMP group (p < .05) while the NAS- group did not. Across the sample, mothers with higher depression scores reported higher infant "unsettled-irregularity" MABS scores, regardless of group status. Agreement between maternal reports of infant regulatory behaviors and observer-assessed NNNS summary scares was poor in both the NAS+ and COMP groups. CONCLUSIONS Postpartum women in opioid recovery with infants requiring pharmacological intervention for NAS are more at risk for depression which may adversely influence their perceptions of their infants' regulatory profiles. Unique, targeted attachment interventions may be needed for this population.

Abstract
Infants and children with prenatal opioid exposure generally have development within the normal range; however, they seem to be at risk for behavioral problems and for lower scores on cognitive, language, and motor assessments than children without prenatal opioid exposure. It is as of yet unclear whether prenatal opioid exposure itself causes issues with development and behavior, or whether it is simply correlated, due to other confounding factors.

Abstract
INTRODUCTION Rates of neonatal opioid withdrawal syndrome (NOWS) have paralleled the rise of opioid use during pregnancy. While short-term phenotypic symptoms of NOWS are well defined, molecular implications and long-term effects are not well understood. Preferred and first-line of treatment for NOWS includes non-pharmacological interventions; however, more than half of the NOWS neonates will need pharmacologics, with opioids as the primary pharmacological treatment. While effective at reducing symptoms, treating NOWS with opioids is paradoxical given that molecular and long-term developmental consequences with such exposure are unknown. There is a pressing need for a synthesis of current and potential/ novel treatment options for NOWS. METHODS AND ANALYSIS Following a published framework, a scoping review will be conducted to evaluate NOWS treatment, including established treatment methods and novel methods that may warrant future research and consideration. Using broad search terms, as well as Medical Subject Headings terms, a comprehensive search of PubMed, Cochrane Library, Google Scholar, CINAHL, Web of Science and Scopus, as well as references of selected literature, will take place, followed by a screening procedure to identify included and excluded articles. Included studies must address NOWS treatment, or opioid withdrawal treatment of any age group, that may or may not have been tested in preclinical or clinical models. Results will summarise the current pharmacological and non-pharmacological treatment methods for NOWS, as well as potential novel treatments with a specific interest in non-opioid pharmacological interventions. ETHICS AND DISSEMINATION This scoping review aims to broadly search preclinical and clinical literature as it relates to treatment of NOWS, including potential novel treatments with a specific interest in non-opioid pharmacological interventions. Given that this study does not directly involve human subjects or animal subjects research, Institutional Review Board (IRB) or Institutional Animal Care and Use Committee (IACUC) approval is not required. Results of this scoping review will be disseminated at conferences and submitted for publication in a peer-reviewed journal.

Abstract
The current opioid epidemic has dramatically increased the number of children who are prenatally exposed to opioids, including oxycodone. A number of social and cognitive abnormalities have been documented in these children as they reach young adulthood. However, little is known about the mechanisms underlying developmental effects of prenatal opioid exposure. Microglia, the resident immune cells of the brain, respond to acute opioid exposure in adulthood. Moreover, microglia are known to sculpt neural circuits during typical development. Indeed, we recently found that microglial phagocytosis of dopamine D1 receptors (D1R) in the nucleus accumbens (NAc) is required for the natural developmental decline in NAc-D1R that occurs between adolescence and adulthood in rats. This microglial pruning occurs only in males, and is required for the normal developmental trajectory of social play behavior. However, virtually nothing is known as to whether this developmental program is altered by prenatal exposure to opioids. Here, we show in rats that maternal oxycodone self-administration during pregnancy leads to reduced adolescent microglial phagocytosis of D1R and subsequently higher D1R density within the NAc in adult male, but not female, offspring. Finally, we show prenatal and adult behavioral deficits in opioid-exposed offspring, including impaired extinction of oxycodone-conditioned place preference in males. This work demonstrates for the first time that microglia play a key role in translating prenatal opioid exposure to changes in neural systems and behavior.

Abstract
Purpose The aims of this study were, in a cohort of children with neonatal opioid withdrawal syndrome (NOWS), (a) to report 1-year neurodevelopmental outcomes and specifically characterize speech, language, and hearing outcomes and (b) to report the prevalence of cleft lip and/or cleft palate. Method This prospective observational cohort study includes newborns with confirmed in utero opioid exposure who received pharmacological treatment for NOWS. During 1-year-old developmental visits, we administered standardized assessments (Bayley Scales of Infant and Toddler Development-Third Edition [Bayley-III] or Developmental Assessment of Young Children-Second Edition [DAYC-2]-due to COVID-19 restrictions). We compared Bayley-III scores to standardized population means using one-sample z tests. We report estimates, 95% confidence intervals, and two-sided p values. Results We enrolled 202 infants (October 2018 to March 2020). Follow-up at 1-year was 80%. Infants with NOWS had lower Bayley-III scores at 1 year compared to published norms for cognitive, language, and motor domains. One infant with NOWS was diagnosed with isolated cleft palate and Pierre Robin sequence. All infants passed the newborn hearing screen, and 7.5% had a formal hearing evaluation after neonatal intensive care unit discharge, with 40% having abnormal or inconclusive results; middle ear effusion was the leading cause of abnormal hearing (66.7%). Ten percent of children received a speech-language pathology referral prior to 2 years of age. Infants born to mothers with mental health conditions were more likely to have Bayley-III or DAYC-2 scores below 95 in language or motor domains. Conclusions Infants with pharmacologically treated NOWS have significantly lower cognitive, language, and motor scores on standardized developmental testing compared to population means at 1 year of age. Early speech-language pathology referral is frequently necessary to promote optimal development in this population. Supplemental Material https://doi.org/10.23641/asha.20044403.

Effect of Prenatal Opioid Exposure on the Human Placental Methylome. Biomedicines 2022; 10:biomedicines10051150.

Abstract
Prenatal exposure to addictive drugs can lead to placental epigenetic modifications, but a methylome-wide evaluation of placental DNA methylation changes after prenatal opioid exposure has not yet been performed. Placental tissue samples were collected at delivery from 19 opioid-exposed and 20 unexposed control full-term pregnancies. Placental DNA methylomes were profiled using the Illumina Infinium HumanMethylationEPIC BeadChip. Differentially methylated CpG sites associated with opioid exposure were identified with a linear model using the ‘limma’ R package. To identify differentially methylated regions (DMRs) spanning multiple CpG sites, the ‘DMRcate’ R package was used. The functions of genes mapped by differentially methylated CpG sites and DMRs were further annotated using Enrichr. Differentially methylated CpGs (n = 684, unadjusted p < 0.005 and |∆β| ≥ 0.05) were mapped to 258 genes (including PLD1, MGAM, and ALCS2). Differentially methylated regions (n = 199) were located in 174 genes (including KCNMA1). Enrichment analysis of the top differentially methylated CpG sites and regions indicated disrupted epigenetic regulation of genes involved in synaptic structure, chemical synaptic transmission, and nervous system development. Our findings imply that placental epigenetic changes due to prenatal opioid exposure could result in placental dysfunction, leading to abnormal fetal brain development and the symptoms of opioid withdrawal in neonates.

Abstract
Opioid use by pregnant women results in neonatal opioid withdrawal syndrome (NOWS) and lifelong neurobehavioral deficits including language impairments. Animal models of NOWS show impaired performance in a two-tone auditory discrimination task, suggesting abnormalities in sensory processing in the auditory cortex. To investigate the consequences of perinatal opioid exposure on auditory cortex circuits, we administered fentanyl to mouse dams in their drinking water throughout gestation and until litters were weaned at postnatal day (P)21. We then used in vivo two-photon Ca2+ imaging in adult animals of both sexes to investigate how primary auditory cortex (A1) function was altered. Perinatally exposed animals showed fewer sound-responsive neurons in A1, and the remaining sound-responsive cells exhibited lower response amplitudes but normal frequency selectivity and stimulus-specific adaptation (SSA). Populations of nearby layer 2/3 (L2/3) cells in exposed animals showed reduced correlated activity, suggesting a reduction of shared inputs. We then investigated A1 microcircuits to L2/3 cells by performing laser-scanning photostimulation (LSPS) combined with whole-cell patch-clamp recordings from A1 L2/3 cells. L2/3 cells in exposed animals showed functional hypoconnectivity of excitatory circuits of ascending inputs from L4 and L5/6 to L2/3, while inhibitory connections were unchanged, leading to an altered excitatory/inhibitory balance. These results suggest a specific reduction in excitatory ascending interlaminar cortical circuits resulting in decreased activity correlations after fentanyl exposure. We speculate that these changes in cortical circuits contribute to the impaired auditory discrimination ability after perinatal opioid exposure.SIGNIFICANCE STATEMENT This is the first study to investigate the functional effects of perinatal fentanyl exposure on the auditory cortex. Experiments show that perinatal fentanyl exposure results in decreased excitatory functional circuits and altered population activity in primary sensory areas in adult mice. These circuit changes might underlie the observed language and cognitive deficits in infants exposed to opioids.

[PMID: 34154813 DOI: 10.1016/j.jpedsurg.2021.05.015] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2021] [Revised: 04/27/2021] [Accepted: 05/17/2021] [Indexed: 11/20/2022]
Abstract
BACKGROUND Epidural anesthesia in infants undergoing open abdominal surgery has the potential to reduce opioid consumption, lower pain scores, and expedite tracheal extubation. We evaluated associations between use of continuous epidural chloroprocaine and improved intra- and post-operative outcomes. METHODS This matched retrospective cohort study first identified 24 patients who between April 2018 through December 2019 were treated with a caudal catheter and epidural chloroprocaine infusion for a laparotomy at postnatal age of 6 months or less. A matched comparator group of 24 patients was derived based on age and type of surgery. Exclusion criteria were the presence of a preoperative opioid infusion, comorbidities that would preclude appropriate pain assessment, or a recent surgical procedure. Primary outcomes included opioid consumption and pain scores; we secondarily analyzed intraoperative anesthetic requirements, other systemic analgesic use, vital signs, tracheal extubation time, and procedural times. RESULTS Treatment with epidural anesthesia was associated with lower 5-day total postoperative opioid consumption (3.2 mg/kg vs. 19.7 mg/kg in the respective epidural vs. systemic groups, p = 0.001) and time to tracheal extubation (1.3 days vs. 3.2 days, p = 0.005). Any statistically significant differences in pain scores were not clinically meaningful. There were no differences in mean arterial pressure or intraoperative inhaled anesthetic doses. CONCLUSION Continuous infusion of epidural chloroprocaine in infants following open abdominal surgery may limit exposure to systemic opioid medications while providing adequate postoperative analgesia and shortening time to tracheal extubation.

Abstract
In utero brain development underpins brain health across the lifespan but is vulnerable to physiological and pharmacological perturbation. Here, we show that antiepileptic medication during pregnancy impacts on cortical activity during neonatal sleep, a potent indicator of newborn brain health. These effects are evident in frequency-specific functional brain networks and carry prognostic information for later neurodevelopment. Notably, such effects differ between different antiepileptic drugs that suggest neurodevelopmental adversity from exposure to antiepileptic drugs and not maternal epilepsy per se. This work provides translatable bedside metrics of brain health that are sensitive to the effects of antiepileptic drugs on postnatal neurodevelopment and carry direct prognostic value.

Abstract
OBJECTIVE A rising incidence in maternal drug use during pregnancy has led to a concomitant rise in neonatal opioid withdrawal syndrome. Despite evidence that drug use during pregnancy affects all demographic groups equally, authors of recent studies have suggested that minority women are tested for drug use more than their counterparts. In this study, we aimed to assess whether toxicology testing of neonates was associated with maternal characteristics. METHODS Retrospective cohort study reviewing charts of neonates born at an urban academic center between January 1, 2018, and December 31, 2018, who underwent toxicology testing. Demographics from tested neonates were taken from mothers' self-reported data and compared with sociodemographics of all mothers with deliveries in 2018, including age, race, marital status, and zip code. Indication for toxicology testing as recorded by ordering clinician was also collected. There were no standardized guidelines for toxicology testing during this study period. RESULTS Of 6438 births in 2018, toxicology testing was sent on 86 neonates (1.3%). Mothers of neonates with testing were younger (P < .0001), less likely to be white (P < .0001), self-reported "single" (P < .0001), and lived in lowest income zip codes (P < .0001). Indications for testing were varied, with the most common indications including maternal substance use disorder (37%) and marijuana use (26%). CONCLUSION Maternal age, race, marital, and socioeconomic status were associated with toxicology testing on neonates, although data suggest that drug use affects all demographic groups. Current practice at our institution may overtest some groups. Evidence-based, standardized guidelines are urgently needed to reduce bias and repercussions of toxicology testing of neonates.

Abstract
BACKGROUND Prenatal opioid exposure has been linked to adverse birth outcomes and delays in infant development. Existing literature is limited by a simple group-differences approach as well as inadequate controls for sociodemographic factors and polysubstance exposure co-occurring with prenatal opioid use. METHOD The current study assessed cumulative opioid exposure (duration of prescribed and illicit opioid use) as a predictor of infant birth outcomes and mother-reported developmental status at three and six months of age, controlling for polysubstance exposure. Participants were predominantly low-income pregnant and peripartum women, oversampled for mothers receiving medication-assisted treatment (MAT) for opioid use disorder. Prenatal opioid and non-opioid substance use were reported by mothers using a Timeline Follow-Back Interview completed during the third trimester and updated postnatally (infant age six months). RESULTS Developmental scores were in the normal range. However, total opioid exposure was positively related to premature birth and inversely related to mother-reported developmental status in specific domains. Associations with three-month fine motor skills and six-month communication skills were robust to controls for polysubstance exposure and sociodemographic covariates. CONCLUSIONS Results suggest unique effects of prenatal opioid exposure on the early development of fine motor and communication skills. Similar findings were obtained for prescribed and illicit opioid use, underscoring developmental risks of both MAT and untreated substance use. Exploratory analyses investigating type and timing of MAT suggest directions for future research.

Abstract
OBJECTIVE To determine the prevalence and odds ratios for cleft lip and/or palate (CL/P) among infants prenatally exposed to opioids with or without neonatal opioid withdrawal syndrome (NOWS). DESIGN This study represents an exploratory, retrospective cohort study design of newborn medical health records from 2011 to 2016. SETTING Records were drawn from a regional health system located in South Central Appalachia. POPULATION AND STUDY SAMPLE The original population yielded 3 cohorts of infants: (1) infants with opioid exposure (OE) but not requiring pharmacological intervention (OE; N = 168); (2) infants with NOWS requiring pharmacological intervention (N = 294); and (3) infants with no opioid exposure (NOE; N = 16 090), the primary comparison group. MAIN OUTCOME Infants in the NOWS and OE groups showed significantly increased prevalence and odds ratios for CL/P when compared to those in the NOE group. RESULTS Prevalence rates per 1000 live births for infants with OE (35.71) and infants with NOWS (6.80) were significantly higher than those for infants with NOE (1.37). Comparison of infants with OE to the NOE group revealed significantly increased odds for CL/P, isolated cleft palate (CP), cleft lip (CL), and cleft lip and palate (CLP) (27.05, 41.81, 19.26, 19.37, respectively; all Ps < .008). The odds ratios for infants with NOWS compared to the NOE group were significantly higher for CL/P and CP (5.00 and 10.98, respectively; Ps < .03) but not for CL and CLP. CONCLUSION The results provide additional evidence that prenatal OE should be considered among the critical environmental risk factors that can contribute to CL/P.
