Abstract
Key recommendations
All women should be assessed at booking (by 14 weeks) for risk factors for fetal growth restriction (FGR) to identify those who require increased surveillance using an agreed pathway [Grade GPP]. Findings at the midtrimester anomaly scan should be incorporated into the fetal growth risk assessment and the risk assessment updated throughout pregnancy. [Grade GPP]
Reduce smoking in pregnancy by identifying women who smoke with the assistance of carbon monoxide (CO) testing and ensuring in‐house treatment from a trained tobacco dependence advisor is offered to all pregnant women who smoke, using an opt‐out referral process. [Grade GPP]
Women at risk of pre‐eclampsia and/or placental dysfunction should take aspirin 150 mg once daily at night from 12+0–36+0 weeks of pregnancy to reduce their chance of small‐for‐gestational‐age (SGA) and FGR. [Grade A]
Uterine artery Dopplers should be carried out between 18+0 and 23+6 weeks for women at high risk of fetal growth disorders [Grade B]. In a woman with normal uterine artery Doppler and normal fetal biometry at the midtrimester scan, serial ultrasound scans for fetal biometry can commence at 32 weeks. Women with an abnormal uterine artery Doppler (mean pulsatility index > 95th centile) should commence ultrasound scans at 24+0–28+6 weeks based on individual history. [Grade B]
Women who are at low risk of FGR should have serial measurement of symphysis fundal height (SFH) at each antenatal appointment after 24+0 weeks of pregnancy (no more frequently than every 2 weeks). The first measurement should be carried out by 28+6 weeks. [Grade C]
Women in the moderate risk category are at risk of late onset FGR so require serial ultrasound scan assessment of fetal growth commencing at 32+0 weeks. For the majority of women, a scan interval of four weeks until birth is appropriate. [Grade B]
Maternity providers should ensure that they clearly identify the reference charts to plot SFH, individual biometry and estimated fetal weight (EFW) measurements to calculate centiles. For individual biometry measurements the method used for measurement should be the same as those used in the development of the individual biometry and fetal growth chart [Grade GPP]. For EFW the Hadlock three parameter model should be used. [Grade C]
Maternity providers should ensure that they have guidance that promotes the use of standard planes of acquisition and calliper placement when performing ultrasound scanning for fetal growth assessment. Quality control of images and measurements should be undertaken. [Grade C]
Ultrasound biometry should be carried out every 2 weeks in fetuses identified to be SGA [Grade C]. Umbilical artery Doppler is the primary surveillance tool and should be carried out at the point of diagnosis of SGA and during follow‐up as a minimum every 2 weeks. [Grade B]
In fetuses with an EFW between the 3rd and 10th centile, other features must be present for birth to be recommended prior to 39+0 weeks, either maternal (maternal medical conditions or concerns regarding fetal movements) or fetal compromise (a diagnosis of FGR based on Doppler assessment, fetal growth velocity or a concern on cardiotocography [CTG]) [Grade C]. For fetuses with an EFW or abdominal circumference less than the 10th centile where FGR has been excluded, birth or the initiation of induction of labour should be considered at 39+0 weeks after discussion with the woman and her partner/family/support network. Birth should occur by 39+6 weeks. [Grade B]
Pregnancies with early FGR (prior to 32+0 weeks) should be monitored and managed with input from tertiary level units with the highest level neonatal care. Care should be multidisciplinary by neonatology and obstetricians with fetal medicine expertise, particularly when extremely preterm (before 28 weeks) [Grade GPP]. Fetal biometry in FGR should be repeated every 2 weeks [Grade B]. Assessment of fetal wellbeing can include multiple modalities but must include computerised CTG and/or ductus venous. [Grade B]
In pregnancies with late FGR, birth should be initiated from 37+0 weeks to be completed by 37+6 weeks [Grade A]. Decisions for birth should be based on fetal wellbeing assessments or maternal indication. [Grade GPP]

Abstract
INTRODUCTION Cannabis potency and its use during pregnancy have increased in the last decade. The aim of this study was to investigate the impact of antenatal cannabis use on fetal growth, preterm birth and other perinatal outcomes. MATERIAL AND METHODS A propensity score-matched analysis was performed in women with singleton pregnancies attending a tertiary care site in Barcelona. Women in the cannabis group were selected based on the results of a detection test. Primary outcomes were small for gestational age at birth (SGA), low birthweight and preterm birth. Secondary outcomes were other biometric parameters (neonatal length and head circumference), respiratory distress, admission to the neonatal intensive care unit and breastfeeding at discharge. A second propensity score-matched analysis excluding other confounders (use of other recreational drugs and discontinuation of cannabis use during pregnancy) was performed. RESULTS Antenatal cannabis was associated with a higher odds ratio of SGA (OR 3.60, 95% CI: 1.68-7.69), low birthweight (OR 3.94, 95% CI: 2.17-7.13), preterm birth at 37 weeks (OR 2.07, 95% CI: 1.12-3.84) and 32 weeks of gestation (OR 4.13, 95% CI: 1.06-16.11), admission to the neonatal intensive care unit (OR 1.95, 95% CI: 1.03-3.71), respiratory distress (OR 2.77, 95% CI: 1.26-6.34), and lower breastfeeding rates at discharge (OR 0.10, 95% CI: 0.05-0.18). When excluding other confounders, no significant association between antenatal cannabis use and SGA was found. CONCLUSIONS Antenatal cannabis use increases the risk of SGA, low birthweight, preterm birth and other adverse perinatal outcomes. However, when isolating the impact of cannabis use by excluding women who use other recreational drugs and those who discontinue cannabis during pregnancy, no significant association between antenatal cannabis use and SGA birth was found.

Association between maternal cigarette smoking cessation and risk of preterm birth in Western New York. Paediatr Perinat Epidemiol 2024; 38:316-326. [PMID: 38558461 DOI: 10.1111/ppe.13075] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2024] [Revised: 02/20/2024] [Accepted: 03/07/2024] [Indexed: 04/04/2024]
Abstract
BACKGROUND Although many studies suggested the benefit of smoking cessation among pregnant women in reducing the risk of preterm birth (PTB), the timing of the effect of the cessation remains inconclusive. OBJECTIVES To examine the association of trimester-specific smoking cessation behaviours with PTB risk. METHODS We included 199,453 live births in Western New York between 2004 and 2018. Based on self-reported cigarette smoking during preconception and in each trimester, we created six mutually exclusive groups: non-smokers, quitters in each trimester, those who smoked throughout pregnancy, and inconsistent smokers. Risk ratios (RRs) and 95% confidence intervals (CIs) were estimated using Poisson regression to examine the association between smoking cessation and PTB. Effect modification by illegal drug use, maternal age, race and ethnicity and pre-pregnancy body mass index (BMI) was investigated multiplicatively by ratio of relative risk and additively by relative excess risk due to interaction (RERI). RESULTS Overall, 6.7% of women had a PTB; 14.1% smoked throughout pregnancy and 3.4%, 1.8% and 0.8% reported quitting smoking during the first, second and third trimesters, respectively. Compared to non-smokers, third-trimester cessation (RR 1.20, 95% CI 1.01, 1.43) and smoking throughout pregnancy (RR 1.27, 95% CI 1.21, 1.33) were associated with a higher PTB risk, while quitting smoking during the first or second trimester, or inconsistent smoking was not associated with PTB. A positive additive interaction was identified for maternal age and late smoking cessation or smoking throughout pregnancy on PTB risk (RERI 0.17, 95% CI 0.00, 0.36), and a negative interaction was observed for pre-pregnancy BMI ≥30 kg/m2 (ratio of relative risk 0.70, 95% CI 0.63, 0.78; RERI -0.42, 95% CI -0.56, -0.30). CONCLUSION Compared to non-smokers, smoking throughout pregnancy and third-trimester smoking cessation are associated with an increased risk of PTB, while quitting before the third trimester may not increase PTB risk.

Abstract
BACKGROUND Evidence of associations between prenatal cannabis use (PCU) and maternal and infant health outcomes remains conflicting amid broad legalization of cannabis across Canada and 40 American states. A critical limitation of existing evidence lies in the non-standardized and crude measurement of prenatal cannabis use (PCU), resulting in high risk of misclassification bias. We developed a standardized tool to comprehensively measure prenatal cannabis use in pregnant populations for research purposes. METHODS We conducted a mixed-methods, patient-oriented tool development and validation study, using a bias-minimizing process. Following an environmental scan and critical appraisal of existing prenatal substance use tools, we recruited pregnant participants via targeted social media advertising and obstetric clinics in Alberta, Canada. We conducted individual in-depth interviews and cognitive interviewing in separate sub-samples, to develop and refine our tool. We assessed convergent and discriminant validity internal consistency and 3-month test-retest reliability, and validated the tool externally against urine-THC bioassays. RESULTS Two hundred fifty four pregnant women participated. The 9-item Cannabis Exposure in Pregnancy Tool (CEPT) had excellent discriminant (Cohen's kappa = -0.27-0.15) and convergent (Cohen's kappa = 0.72-1.0) validity; as well as high internal consistency (Chronbach's alpha = 0.92), and very good test-retest reliability (weighted Kappa = 0.92, 95% C.I. [0.86-0.97]). The CEPT is valid against urine THC bioassay (sensitivity = 100%, specificity = 82%). CONCLUSION The CEPT is a novel, valid and reliable measure of frequency, timing, dose, and mode of PCU, in a contemporary sample of pregnant women. Using CEPT (compared to non-standardized tools) can improve measurement accuracy, and thus the quality of research examining PCU and maternal and child health outcomes.

Abstract
Objective: To determine whether prenatal cannabis use alone increases the likelihood of fetal and neonatal morbidity and mortality. Study Design: We searched bibliographic databases, such as PubMed, Embase, Scopus, Cochrane reviews, PsycInfo, MEDLINE, Clinicaltrials.gov, and Google Scholar from inception through February 14, 2022. Cohort or case-control studies with prespecified fetal or neonatal outcomes in pregnancies with prenatal cannabis use. Primary outcomes were preterm birth (PTB; <37 weeks of gestation), small-for-gestational-age (SGA), birthweight (grams), and perinatal mortality. Two independent reviewers screened studies. Studies were extracted by one reviewer and confirmed by a second using a predefined template. Risk of bias assessment of studies, using the Newcastle-Ottawa Quality Assessment Scale, and Grading of Recommendations Assessment, Development, and Evaluation for evaluating the certainty of evidence for select outcomes were performed by two independent reviewers with disagreements resolved by a third. Random effects meta-analyses were conducted, using adjusted and unadjusted effect estimates, to compare groups according to prenatal exposure to cannabis use status. Results: Fifty-three studies were included. Except for birthweight, unadjusted and adjusted meta-analyses had similar results. We found very-low- to low-certainty evidence that cannabis use during pregnancy was significantly associated with greater odds of PTB (adjusted odds ratio [aOR], 1.42; 95% confidence interval [CI], 1.19 to 1.69; I2, 93%; p=0.0001), SGA (aOR, 1.76; 95% CI, 1.52 to 2.05; I2, 86%; p<0.0001), and perinatal mortality (aOR, 1.5; 95% CI, 1.39 to 1.62; I2, 0%; p<0.0001), but not significantly different for birthweight (mean difference, -40.69 g; 95% CI, -124.22 to 42.83; I2, 85%; p=0.29). Because of substantial heterogeneity, we also conducted a narrative synthesis and found comparable results to meta-analyses. Conclusion: Prenatal cannabis use was associated with greater odds of PTB, SGA, and perinatal mortality even after accounting for prenatal tobacco use. However, our confidence in these findings is limited. Limitations of most existing studies was the failure to not include timing or quantity of cannabis use. This review can help guide health care providers with counseling, management, and addressing the limited existing safety data. Protocol Registration: PROSPERO CRD42020172343.

Abstract
Prenatal cannabis use is associated with adverse offspring neurodevelopmental outcomes, however the underlying mechanisms are relatively unknown. We sought to determine the impact of chronic delta-9-tetrahydrocannabinol (THC) exposure on fetal neurodevelopment in a rhesus macaque model using advanced imaging combined with molecular and tissue studies. Animals were divided into two groups, control (n = 5) and THC-exposed (n = 5), which received a daily THC edible pre-conception and throughout pregnancy. Fetal T2-weighted MRI was performed at gestational days 85 (G85), G110, G135 and G155 to assess volumetric brain development. At G155, animals underwent cesarean delivery with collection of fetal cerebrospinal fluid (CSF) for microRNA (miRNA) studies and fetal tissue for histologic analysis. THC exposure was associated with significant age by sex interactions in brain growth, and differences in fetal brain histology suggestive of brain dysregulation. Two extracellular vesicle associated-miRNAs were identified in THC-exposed fetal CSF; pathway analysis suggests that these miRNAs are associated with dysregulated axonal guidance and netrin signaling. This data is indicative of subtle molecular changes consistent with the observed histological data, suggesting a potential role for fetal miRNA regulation by THC. Further studies are needed to determine whether these adverse findings correlate with long-term offspring neurodevelopmental health.

Abstract
Objectives: To examine perceived risk of harm from weekly cannabis use among reproductive-aged women with disabilities. Methods: Using data from the 2021 National Survey on Drug Use and Health, we assessed perceived risk of harm associated with weekly cannabis use among women of reproductive age by disability status. Disabilities included sensory, cognitive, and those related to daily activities. Logistic regression was employed to examine correlates of risk perception associated with weekly cannabis in this subpopulation of women. Results: A significantly higher percentage of women with any disability perceived no risk associated with weekly cannabis use (37.9%) compared to those with no disabilities (26.1%). Approximately, 60.0% of women with disabilities who used cannabis in the past 12 months perceived no risk of harm from weekly cannabis use. Overall, women with disabilities and cannabis use in the past 12 months had higher adjusted odds (AOR=2.90, 95% CI=2.10-4.10) of perceiving no risk associated with weekly use of cannabis compared to women without any disability and no cannabis use. Other significant factors associated with an increased likelihood of perceiving no risk of harm from weekly use of cannabis included younger women, having higher income, being in good health, and using alcohol or tobacco. Conclusions: Perceived risk of harm associated with weekly cannabis use is particularly low among women with disabilities who use cannabis. Given current attitudes toward cannabis as a harmless drug, and the potential adverse health outcomes, it is imperative to monitor and understand women's perceptions of risk of harm from cannabis use for clinical guidance, provider and patient education, and public health programs to support evidence-based approaches in addressing its use among vulnerable populations such as those of reproductive age with disabilities.

Abstract
Stigma toward pregnant and postpartum people who use drugs is common and seeks to define addiction as a moral weakness rather than a chronic medical illness that requires resources and treatment. More concerning is the additive impact of substance use and racial discrimination, whose intersections present particularly challenging circumstances. In this article, the authors review the history of substance use in the United States and focus on 3 substances of abuse that illustrate the inequity faced by pregnant person of color who use drugs.

Torres J, Miller C, Apostol M, Gross J, Maxwell JR. The impact of recreational cannabinoid legalization on utilization in a pregnant population. Front Public Health 2024; 12:1278834. [PMID: 38444440 PMCID: PMC10912290 DOI: 10.3389/fpubh.2024.1278834] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Accepted: 02/02/2024] [Indexed: 03/07/2024] Open
Abstract
Background Marijuana potency and utilization both continue to increase across the United States. While the overall prevalence of cannabinoid utilization during pregnancy has been surveyed in various studies, the direct impact of changing governmental policies on pregnancy use is less characterized. Thus, we aimed to investigate how the legalization of recreational cannabinoid products impacted use during pregnancy in the state of New Mexico. Methods Participants who had a live birth during two study epochs were included: pre-legalization (Epoch 1: 1 January 2019-31 March 2021) and post-legalization (Epoch 2: 1 November 2021-30 November 2022). Participants were further divided into case group [prenatal cannabinoid exposure (PCE)] vs. control (no PCE), with cases being identified by documented self-report or a positive laboratory toxicology test for cannabinoid use during pregnancy. Results A total of 1,191 maternal/infant dyads were included in Epoch 1, and 378 maternal/infant dyads were included in Epoch 2. In Epoch 1, 788 dyads were controls with 403 cases, while Epoch 2 had 292 controls and 86 cases. Interestingly there was a significant decrease in self-report or positive laboratory toxicology tests in Epoch 2 compared to Epoch 1. Infants born following PCE in both Epoch groups were more commonly born via Cesarean section, had significantly smaller birth weight, length, and head circumference as well as significantly lower Apgar scores at 1 and 5 min. Conclusion The finding of decreased reported cannabinoid use in the post-legalization group is contradictory to previous studies which have shown increased rates of cannabinoid use after legalization. This could be due to multiple factors including changes in screening practices, the COVID-19 pandemic, and lack of commercialization of THC products. Additional studies are needed to further characterize how changing governmental policies impacts utilization during pregnancy.

Abstract
OBJECTIVE Our primary objective was to understand breastfeeding individuals' decisions to use cannabis. Specifically, we investigated reasons for cannabis use, experiences with healthcare providers regarding use, and potential concerns about cannabis use. METHODS We collected survey data from twenty breastfeeding participants from Washington and Oregon who used cannabis at least once weekly. We documented individuals' cannabis use and analyzed factors associated with their decisions to use cannabis during lactation. Qualitative description was used to assess responses to an open-ended question about potential concerns. RESULTS Fifty-five percent of participants (n = 11) reported using cannabis to treat or manage health conditions, mostly related to mental health. Eighty percent of participants (n = 16) reported very few or no concerns about using cannabis while breastfeeding, although participants who used cannabis for medical purposes had significantly more concerns. Most participants (n = 18, 90%) reported receiving either no or unhelpful advice from healthcare providers. Four themes arose through qualitative analysis, indicating that breastfeeding individuals are: 1) identifying research gaps and collecting evidence; 2) monitoring their child's health and development; 3) monitoring and titrating their cannabis use; and 4) comparing risks between cannabis and other controlled substances. CONCLUSIONS Breastfeeding individuals reported cannabis for medical and non-medical reasons and few had concerns about cannabis use during breastfeeding. Breastfeeding individuals reported using a variety of strategies and resources in their assessment of risk or lack thereof when deciding to use cannabis. Most participants reported receiving no helpful guidance from healthcare providers.

Abstract
BACKGROUND Marijuana is the most commonly used federally illicit substance among reproductive-age women in the United States. Updated information on marijuana use in this population can inform clinical and public health interventions. METHODS Data from the 2013-2019 National Survey on Drug Use and Health was used to report weighted prevalence estimates of marijuana use in the past month, past 2-12 months, and past year among women aged 18-44 years with self-reported pregnancy status. Bivariate analyses and general linear regression models with Poisson distribution using appropriate survey procedures identified factors associated with past-year marijuana use by pregnancy status. RESULTS Among pregnant women, 4.9% (95% confidence interval [CI]: 4.1-5.6) reported marijuana use in the past month, 10.4% (95% CI: 9.3-11.5) in the past 2-12 months, and 15.2% (95% CI: 13.9-16.6) in the past year. Among nonpregnant women, 11.8% (95% CI: 11.5-12.0) reported marijuana use in the past month, 7.8% (95% CI: 7.6-8.0) in the past 2-12 months, and 19.5% (95% CI: 19.2-19.9) in the past year. After adjusting for sociodemographic characteristics, past-year marijuana use was 2.3-5.1 times more likely among pregnant, and 2.1 to 4.6 times more likely among nonpregnant women who reported past-year tobacco smoking, alcohol use, or other illicit drug use compared to those reporting no substance use. CONCLUSIONS Pregnant and nonpregnant women reporting marijuana use, alone or with other substances, can benefit from substance use screening and treatment facilitation.

Abstract
Cannabinoid use in all populations is increasing as legalization across the United States continues. Concerningly, there is a lack of caution provided by medical providers to pregnant individuals as to the impact the use of cannabinoids could have on the developing fetus. Research continues in both the preclinical and clinical areas, and is severely needed, as the potency of delta-9-tetrahydrocannabinol (THC), the primary psychoactive component of cannabis, has increased dramatically since the initial studies were completed. Thus far, clinical studies raise compelling evidence for short term memory deficits, impulse control issues, and attention deficiencies following prenatal cannabinoid exposure (PCE). These changes may be mediated through epigenetic modifications that not only impact the current offspring but could carry forward to future generations. While additional studies are needed, a pregnancy pause from cannabinoid products should be strongly recommended by providers to ensure the optimal health and well-being of our future generations.

Abstract
Breastfeeding is the gold standard of infant nutrition and current guidelines suggest exclusive breastfeeding for 6 months, with continued breastfeeding through 24 months or beyond. Obstetric care professionals can encourage and educate their patients about breastfeeding through the prenatal period when many expectant parents make decisions about their infant feeding choices. Education and support should extend through the postpartum period and include parents who may have concerns surrounding medical comorbidities, breast augmentation, or substance use disorders.

Abstract
BACKGROUND The effect of prenatal marijuana exposure (PME) on child neurodevelopment remains poorly understood. Prior studies have demonstrated inconsistent results. OBJECTIVES This study evaluated the association between PME and neuropsychological test scores in late childhood and early adulthood, accounting for a wide range of parental characteristics. METHODS This study evaluated participants from the Raine Study, a cohort of 2868 children born between 1989 and 1992. Children whose mothers provided information on marijuana use during pregnancy were included. The primary outcome was the Clinical Evaluation of Language Fundamentals (CELF) at age 10. Secondary outcomes included the Peabody Picture Vocabulary Test (PPVT), Child Behaviour Checklist (CBCL), McCarron Assessment of Neuromuscular Development (MAND), Coloured Progressive Matrices (CPM), Symbol Digit Modality Test (SDMT) and Autism Spectrum Quotient (AQ) scores. Exposed and unexposed children were matched by propensity score using optimal full matching. Missing covariate data were imputed using multiple imputation. Inverse probability of censoring weighting (IPCW) was used to adjust for missing outcome data. Linear regression within matched sets, adjusted by IPCW, evaluated score differences between exposed and unexposed children. As a secondary analysis, modified Poisson regression, adjusted by match weights and IPCW, evaluated the risk of clinical deficit in each outcome following PME. RESULTS Of the 2804 children in this cohort, 285 (10.2%) had PME. After optimal full matching and IPCW, exposed children scored similarly on CELF Total (-0.33 points, 95% confidence interval [CI] -4.71, 4.05), Receptive (+0.65 points, 95% CI -4.08, 5.38) or Expressive (-0.53 points, 95% CI -5.07, 4.02). PME was not associated with secondary outcomes or risks of clinical deficit in any neuropsychological assessments. CONCLUSIONS After adjusting for sociodemographic and clinical covariates, PME was not associated with worse neuropsychological test scores at age 10 or autistic traits at 19-20.

Abstract
Background: Adverse childhood experiences (ACEs) are associated with substance use later in life, including marijuana use. It is unknown whether these behaviors extend to lactating women. Our objective was to examine the association between childhood ACE and marijuana use in lactating individuals and determine whether positive childhood experiences (PCEs) modified this association. Methods: This study included 617 lactating individuals from the UC San Diego Human Milk Research Biorepository enrolled from 2015 to 2020. ACE and PCE histories were assessed by the Positive and Adverse Childhood Experiences questionnaire. Past 2-week marijuana use was self-reported at enrollment. Multivariable log-linear regressions were used to calculate adjusted risk ratios (aRRs) and 95% confidence intervals (CIs) for ACE history and marijuana use, and to assess modification by PCE. Results: Marijuana use during lactation was higher among individuals who reported three or more ACEs (aRR = 2.58, 95% CI = 1.23-5.44), household dysfunction (aRR = 3.08, 95% CI = 1.17-8.10), sexual abuse (aRR = 2.25, 95% CI = 1.08-4.68), or physical abuse (aRR = 2.10, 95% CI = 1.02-4.13). There was no association between emotional abuse and marijuana use during lactation. There was no effect modification by PCEs. Conclusion: Higher ACE frequency, and specifically history of household dysfunction, physical abuse, or sexual abuse increased risk for marijuana use during lactation. Because of marijuana's potential adverse effects on the infant through human milk, postpartum ACE screening is warranted.

Abstract
Care of the newborn infant is a critical skill for general pediatricians and other providers in the practice of pediatric medicine. Optimal care relies on a thorough understanding of risk factors that may be present during the pregnancy and delivery, as well as the ability to recognize and address unanticipated problems in the postnatal period. This article focuses on antenatal care of the newborn, issues that present in the immediate postdelivery period, and care of the newborn after discharge. It also includes updated information on current topics in pediatric practice, such as the importance of vaccination, parental hesitancy in accepting common medical interventions, and updated guidelines related to the coronavirus disease 2019 pandemic. At the conclusion of the article, the reader should have a general understanding of antenatal risk factors that could affect the transition from the intrauterine environment and have the knowledge to address common issues that arise in the care of newborn infants.

Abstract
OBJECTIVE Marijuana (MJ) use is associated with adverse effects on fetal growth. We aimed to investigate the timing of suboptimal fetal growth onset in MJ-exposed pregnancies. In addition, we aimed to explore the relationship between MJ-exposure and both abnormal uterine artery (UtA) Doppler parameters and small for gestational age (SGA). STUDY DESIGN This was a secondary analysis of a prospective multicenter cohort that enrolled nulliparous individuals delivering non-anomalous fetuses beyond 20 weeks' gestation. Marijuana exposure was ascertained by self-report or clinical urine toxicology testing. Ultrasound estimated fetal weights (EFWs) were assessed in participants at both 16w0d-21w6d and 22w0d-29w6d. EFWs and birth weight (BW) were converted to weight percentiles (wPCT). EFW and BW wPCTs were calculated using population-based standards. Additionally, a customized standard designed to be applicable to both EFWs and BWs within the same model was also used to allow for EFW to BW percentile trajectories. The primary outcome, longitudinal wPCT, was compared between individuals with and without MJ use in a linear mixed-effects regression model adjusting for tobacco. For modeling, wPCT was smoothed across gestational age; MJ was estimated as an intercept and linear difference in the slope of gestational age. UtA Doppler notching, resistance index (RI), and pulsatility index (PI) at 16w0d-21w6d were compared using t-test and χ2. SGA at delivery was also compared. RESULTS Nine thousand one hundred and sixty-three individuals met inclusion criteria; 136 (1.5%) used MJ during pregnancy. Individuals who used MJ were more likely to be younger, identify as non-Hispanic Black, and have had less education. Fetuses exposed to MJ had lower wPCT beginning at 28 weeks using population-based and customized standards, when compared to those without exposure. UtA notching, PI, and RI were similar between groups. SGA was more frequent in neonates exposed to MJ using both population-based (22 vs. 9%, p<.001) and customized (25 vs. 14%, p<.001) curves. CONCLUSIONS MJ-exposed fetuses were estimated to be smaller than unexposed fetuses starting at 28 weeks' gestation across both growth standards without a difference in UtA Doppler parameters.

Abstract
Cannabis use in pregnancy is associated with adverse perinatal outcomes, which are likely mediated by the placenta. However, the underlying mechanisms and specific vasoactive effects of cannabis on the placenta are unknown. Our objective was to determine the impact of chronic prenatal delta-tetrahydrocannabinol (THC, main psychoactive component of cannabis) exposure on placental function and development in a rhesus macaque model using advanced imaging. Animals were divided into two groups, control (CON, n = 5) and THC-exposed (THC, n = 5). THC-exposed animals received a THC edible daily pre-conception and throughout pregnancy. Animals underwent serial ultrasound and MRI at gestational days 85 (G85), G110, G135 and G155 (full term is ~ G168). Animals underwent cesarean delivery and placental collection at G155 for histologic and RNA-Seq analysis. THC-exposed pregnancies had significantly decreased amniotic fluid volume (p < 0.001), placental perfusion (p < 0.05), and fetal oxygen availability (p < 0.05), all indicators of placental insufficiency. Placental histological analysis demonstrated evidence of ischemic injury with microinfarctions present in THC-exposed animals only. Bulk RNA-seq demonstrated that THC alters the placental transcriptome and pathway analysis suggests dysregulated vasculature development and angiogenesis pathways. The longer-term consequences of these adverse placental findings are unknown, but they suggest that use of THC during pregnancy may deleteriously impact offspring development.

Abstract
OBJECTIVE This study aimed to determine the factors associated with positive infant drug screen and create a shortened screen and a prediction model. STUDY DESIGN This is a retrospective cohort study of all infants who were tested for drugs of abuse from May 2012 through May 2014. The primary outcome was positive infant urine or meconium drug test. Multivariable logistic regression was used to identify independent risk factors. A combined screen was created, and test characteristics were analyzed. RESULTS Among the 3,861 live births, a total of 804 infants underwent drug tests. Variables associated with having a positive infant test were (1) positive maternal urine test, (2) substance use during pregnancy, (3) ≤ one prenatal visit, and (4) remote substance abuse; each p-value was less than 0.0001. A model with an indicator for having at least one of these four predictors had a sensitivity of 94% and a specificity of 69%. Application of this screen to our population would have decreased drug testing by 57%. No infants had a positive urine drug test when their mother's urine drug test was negative. CONCLUSION This simplified screen can guide clinical decision making for determining which infants should undergo drug testing. Infant urine drug tests may not be needed when a maternal drug test result is negative. KEY POINTS · Many common drug screening criteria are not predictive.. · Four criteria predicted positive infant drug tests.. · No infant urine drug test is needed if the mother tests negative..

Abstract
OBJECTIVE To understand reproductive-aged women's marijuana use beliefs and attitudes. METHODS Qualitative research (10 focus groups and 2 bulletin boards) with 95 Washington State women, aged 18 to 44 years, segmented by marijuana-using pregnant/breastfeeding; marijuana-using not-pregnant/breastfeeding; and nonmarijuana users. Participants completed up to 10 survey questions. We used deductive and inductive coding to analyze findings. RESULTS Marijuana-using pregnant/breastfeeding participants use marijuana to manage physical/mental pain and because of stigma, feel guilty, and sometimes hide use. Medicines have failed to address symptoms. Participants perceived marijuana safer than alcohol, tobacco, and illicit substances. Participants believed in the legitimacy of marijuana for health maintenance and want others to take their personally experienced benefits seriously. Participants interpreted lack of conclusive research as marijuana use not being unsafe. They want more information. All segments preferred hearing from other women about marijuana use experiences, with the marijuana-using pregnant/breastfeeding segment feeling strongest about this. CONCLUSIONS Personal experiences with, and anecdotes from family/friends about, the effects of marijuana use during pregnancy/breastfeeding influence marijuana-using participants' decision making. NURSING IMPLICATIONS It is important to speak with perinatal patients in a nonjudgmental/nonthreatening manner that acknowledges why reproductive-aged women may use marijuana and that conveys validation of patients' positive experiences with marijuana and a harm-reduction goal.

Abstract
Introduction: There is widespread acceptance of cannabis for medical or recreational use across the society, including pregnant women. Concerningly, numerous studies find that the developing central nervous system (CNS) is vulnerable to the detrimental effects of Δ9-tetrahydrocannabinol (THC). In contrast, almost nothing on the consequences of perinatal cannabidiol (CBD) exposure. In this study, we used mice to investigate the adult impact of perinatal cannabinoid exposure (PCE) with THC, CBD, or a 1:1 ratio of THC and CBD on behaviors. Furthermore, the lasting impact of PCE on fluoxetine sensitivity in the forced swim test (FST) was evaluated to probe neurochemical pathways interacting with the endocannabinoid system (ECS). Methods: Pregnant CD1 dams were injected subcutaneously daily with vehicle, 3 mg/kg THC, 3 mg/kg CBD, or 3 mg/kg THC +3 mg/kg CBD from gestational day 5 to postnatal day 10. Mass spectroscopic (MS) analyses were conducted to measure the THC and CBD brain levels in dams and their embryonic progenies. PCE adults were subjected to a battery of behavioral tests: open field arena, sucrose preference test, marble burying test, nestlet shredding test, and FST. Results: MS analysis found substantial levels of THC and CBD in embryonic brains. Our behavioral testing found that PCE females receiving THC or CBD buried significantly more marbles than control mice. Interestingly, PCE males receiving CBD or THC+CBD had significantly increased sucrose preference. While PCE with THC or CBD did not affect FST immobility, PCE with THC or CBD prevented fluoxetine from decreasing immobility in both males and females. Excitingly, fatty acid amide hydrolase (FAAH) inhibition with a dose of URB597 that was behaviorally inactive in the FST rescued fluoxetine efficacy in PCE mice of both sexes. Conclusions: Our data suggest that PCE with either THC, CBD, or THC+CBD alters repetitive and hedonic behaviors in a phytocannabinoid and sex-dependent manner. In addition, PCE with THC or CBD prevents fluoxetine from enhancing coping behavior. The restoration of fluoxetine responsiveness in THC or CBD PCE adults by inhibition of FAAH suggests that PCE causes a lasting reduction of the ECS and that enhancement of anandamide signaling represents a potential treatment for behavioral deficits following PCE.

Abstract
Within this review, the literature and outcomes from animal models of maternal marijuana use and cigarette smoking are summarized. The existing data demonstrate that prenatal marijuana and nicotine exposure both have multifaceted adverse effects on maternal, gestational, placental, and fetal outcomes. These include placental function and development, fetal growth and birth weight, and offspring neurodevelopment.

Abstract
Tobacco and marijuana are the most common drugs of abuse among pregnant women. Cigarettes have been extensively studied and increase the risk of miscarriage, preterm birth, premature rupture of membranes, placental dysfunction, low birth rate, stillbirth, and infant mortality. There are sparse data on the specific effects of electronic cigarettes and smokeless tobacco in pregnancy. Literature on marijuana in pregnancy is limited by confounding, bias, and the retrospective nature of studies that do not capture contemporary trends in use. However, several studies suggest an association between marijuana and fetal growth restriction, low birth weight, and neurodevelopmental differences in offspring.

Abstract
With the increase in cannabis use due to policy changes and areas of decriminalization, it is important to recognize the potential impact of these substances on endocrine processes. Cannabinoids have many effects by activating the endocannabinoid system. This system plays a role in the normal functioning of nearly every organ and consists of the body's natural endocannabinoids, the cannabinoid receptors, and the enzymes and processes that regulate endocannabinoids. Exogenous cannabinoids such as Δ9-tetrahydrocannabinol (THC) are known to act through cannabinoid type 1 and 2 receptors, and have been shown to mimic endocannabinoid signaling and affect receptor expression. This review summarizes the known impacts of cannabis on thyroid, adrenal, and gonadal function in addition to glucose control, lipids, and bone metabolism, including: reduced female fertility, increased risk of adverse pregnancy outcomes, reduced sperm counts and function, lower thyroid hormone levels with acute use, blunting of stress response with chronic use, increased risk of prediabetes but lower risk of diabetes, suggested improvement of high density lipoproteins and triglycerides, and modest increase in fracture risk. The known properties of endocannabinoids, animal data, population data, and the possible benefits and concerns of cannabinoid use on hormonal function are discussed. The interconnectivity of the endocrine and endocannabinoid systems suggests opportunities for future therapeutic modalities which are an area of active investigation.

Abstract
In 2012, the American Academy of Pediatrics stated that all preterm infant diets should consist of human milk (mother's own milk or pasteurized donor human milk). The clinical reasons supporting this policy are many, including reducing infections and retinopathy of prematurity, decreased neonatal intensive care unit length of stay, subsequent readmissions, a decrease in mortality, and improved neurodevelopmental outcomes. This article focuses on human milk, its composition and bioactive factors, and how it affects the gut-brain axis through the microbiome. We examine how differences between mother's own milk and pasteurized donor human milk affect the premature infant.

Abstract
Abstract
Introduction There is limited research on effective treatment of Hyperemesis Gravidarum (HG), the most extreme version of nausea and vomiting during pregnancy (NVP). This paper
examines current patterns of use and self-reported effectiveness of cannabis/cannabis-based products (CBP) to treat HG.
Materials/Methods The study employed a 21-question survey to gather information on demographics, antiemetic prescription use, and experience with cannabis/CBPs among individuals who
experienced extreme nausea and vomiting or HG during their pregnancy. Age-adjusted unconditional logistic regression was used to compare odds of symptom relief and weight gain between
respondents who used prescription antiemetics and those who used cannabis.
Results Of the 550 survey respondents, 84% experienced weight loss during pregnancy; 96% reported using prescription antiemetics and 14% reported cannabis use for HG. Most
respondents reported using cannabis/CBPs (71%) because their prescribed antiemetics were self-reported to be ineffective. More than half of cannabis/CBP users reported using products daily
or multiple times per day (53%), primarily via smoke inhalation (59%), and mainly either delta-9-tetrahydrocannabinol (THC) only or THC dominant preparations (57%). Eighty-two percent of
cannabis/CBP users reported symptom relief, compared to 60% of prescription antiemetic users. Among patients who reported weight loss during pregnancy, 56% of cannabis users reported gaining
weight within two weeks of treatment, compared to 25% of prescription antiemetic users.
Conclusions Respondents reported using cannabis primarily because prescribed medications were self-reported to be ineffective. Although the survey approach has inherent limitations
so results should be interpreted with caution, in this sample, cannabis was self-reported to be more effective than prescription medications in alleviating HG symptoms and enabling pregnancy
weight gain. Therefore, depending on the safety profiles, randomized, double-blinded, placebo-controlled trials of cannabis compared to other antiemetics are warranted to determine whether
cannabinoids may provide an effective alternative treatment for HG.

Abstract
Introduction Rates of perinatal cannabis use are rising, despite clinical evidence about the potential for harm. Accordingly, pregnant and lactating people who perceive a benefit from cannabis use may have a difficult time making informed decisions about cannabis use. Methods We conducted a systematic review of mixed‐methods research to synthesize existing knowledge on the perspectives of pregnant people and their partners about cannabis use in pregnancy. Six health and social science databases were searched up until May 30, 2021. There were no methodological, time, or geographic limits applied. We employed a convergent integrative approach to the inductive analysis of findings from all studies. Results We identified 26 studies describing views of 17,781 pregnant and postpartum people about cannabis use in pregnancy. No studies describing the views of partners were identified, and only one study specifically addressed the perspectives of lactating people. Comparative analysis revealed that whether cannabis was studied alone or grouped with other substances resulted in significant diversity in descriptions of participant decision‐making priorities and perceptions of risks and benefits. Studies of cannabis alone demonstrated a complex decision‐making process whereby perceived benefits are balanced against the available information about risk, which is often unclear and uncertain. Clear and helpful information was difficult to identify, and health care providers were not described as a helpful and trusted resource for decision‐making. Discussion Decision‐making about cannabis use is difficult for pregnant and lactating people who perceive a benefit from this use, although this decisional difficulty is seldom reflected in studies that examine cannabis as one of multiple substances that pregnant or lactating people may use. Our review suggests several approaches clinicians may take to encourage open and supportive conversations to facilitate informed decisions about cannabis use during the perinatal period.

Abstract
OBJECTIF Fournir aux fournisseurs de soins les meilleures données probantes sur l'utilisation de cannabis et la santé des femmes. Les domaines d'intérêt sont le dépistage, la dépendance et le sevrage; la communication et la tenue de dossier; la grossesse (y compris les issues fœtales et maternelles); la gestion de la douleur maternelle; les soins postnataux (y compris la fumée secondaire et la parentalité); et l'allaitement. POPULATION CIBLE Femmes enceintes, allaitantes ou qui planifient une grossesse. BéNéFICES, RISQUES ET COûTS: Discuter de l'utilisation de cannabis avec les femmes enceintes, allaitantes ou qui planifient une grossesse les aide à faire des choix éclairés. D'après des données probantes limitées, il faut éviter l'utilisation de cannabis pendant la grossesse ou l'allaitement, ou réduire la consommation au maximum si l'abstention n'est pas un objectif atteignable, étant donné l'absence de données sur l'innocuité et le suivi à long terme des grossesses et nourrissons exposés au cannabis. DONNéES PROBANTES: Les auteurs ont interrogé les bases de données PubMed et Cochrane Library pour extraire des articles sur l'utilisation de cannabis pendant la grossesse et l'allaitement publiés entre le 1er janvier 2018 et le 5 février 2021. Les termes de recherche ont été déterminés à partir de termes de recherche MeSH, de mots clés et de leurs variantes : cannabis, cannabinoids, cannabidiol, CBD, THC, marijuana, edible, pregnancy, pregnant, prenatal, perinatal, postnatal, breastfeed, breastfed, lactation, nursing, fetus, fetal, neonatal, newborn et child. Les auteurs ont inclus toutes les publications des types suivants : essais cliniques, études observationnelles, revues (y compris les revues systématiques et les méta-analyses), directives cliniques et déclarations de conférences de consensus. Les principaux critères d'inclusion étaient les femmes enceintes et allaitantes, comme population cible, et l'exposition au cannabis, comme intervention d'intérêt. MéTHODES DE VALIDATION: Les auteurs ont évalué la qualité des données probantes et la force des recommandations en utilisant le cadre méthodologique d'évaluation, de développement et d'évaluation (GRADE).

Abstract
OBJECTIVE To provide health care providers with the best evidence on cannabis use and women's health. Areas of focus include screening, dependence, and withdrawal; communication and documentation; pregnancy (including maternal and fetal outcomes); maternal pain control; postpartum care (including second-hand smoking and parenting); and breastfeeding. TARGET POPULATION The target population includes women who are planning a pregnancy, pregnant, or breastfeeding. BENEFITS, HARMS, AND COSTS Discussing cannabis use with women who are planning a pregnancy, pregnant, or breastfeeding allows them to make informed choices about their cannabis use. Based on the limited evidence, cannabis use in pregnancy or while breastfeeding should be avoided, or reduced as much as possible if abstaining is not feasible, given the absence of safety and long-term follow up data on cannabis-exposed pregnancies and infants. EVIDENCE PubMed and Cochrane Library databases were searched for articles relevant to cannabis use during pregnancy and breastfeeding published between January 1, 2018, and February 5, 2021. The search terms were developed using the MeSH terms and keywords and their variants, including cannabis, cannabinoids, cannabidiol, CBD, THC, marijuana, edible, pregnancy, pregnant, prenatal, perinatal, postnatal, breastfeed, breastfed, lactation, nursing, fetus, fetal, neonatal, newborn, and child. In terms of publication type, all clinical trials, observational studies, reviews (including systematic reviews and meta-analyses), guidelines, and conference consensus statements were included. The main inclusion criteria were pregnant and breastfeeding women as the target population, and exposure to cannabis as the intervention of interest. VALIDATION METHODS The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See online Appendix A (Tables A1 for definitions and A2 for interpretations of strong and weak recommendations). INTENDED AUDIENCE All health care providers who care for women of reproductive age. SUMMARY STATEMENTS RECOMMENDATIONS.

Abstract
OBJECTIVE Marijuana use is associated with placenta-mediated adverse pregnancy outcomes including fetal growth restriction, but the mechanism remains uncertain. The objective was to evaluate the association between maternal marijuana use and the feto-placental weight ratio (FPR). Secondarily, we aimed to compare placental histology of women who used marijuana to those who did not. STUDY DESIGN This was a secondary analysis of singleton pregnancies enrolled in a multicenter and case-control stillbirth study. Prior marijuana use was detected by electronic medical record abstraction or cord homogenate positive for 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid. Prior tobacco use was detected by self-report or presence of maternal serum cotinine. Stillbirths and live births were considered separately. The primary outcome was FPR. Association of marijuana use with FPR was estimated with multivariable linear modeling adjusted for fetal sex, preterm birth, and tobacco use. Comparisons between groups for placental histology were made using Chi-square and stratified by live birth and stillbirth, term and preterm deliveries, and fetal sex. RESULTS Of 1,027 participants, 224 were stillbirths and 803 were live births. Overall, 41 (4%) women used marijuana during the pregnancy. The FPR ratio was lower among exposed offspring but reached statistical significance only for term stillbirths (mean 6.84 with marijuana use vs. mean 7.8 without use, p < 0.001). In multivariable modeling, marijuana use was not significantly associated with FPR (p = 0.09). There were no differences in histologic placental features among those with and without marijuana use overall or in stratified analyses. CONCLUSION Exposure to marijuana may not be associated with FPR. Similarly, there were no placental histologic features associated with marijuana exposure. Further study of the influence of maternal marijuana use on placental development and function is warranted to better understand the association between prenatal marijuana use and poor fetal growth. KEY POINTS · Maternal marijuana exposure was not associated with the feto-placental weight ratio.. · Marijuana exposure was not associated with differences in placental histology.. · Concerning trend toward lower feto-placental weight ratios among marijuana-exposed stillbirths..

Abstract
Background: While national guidelines state that cannabis should not be consumed during pregnancy, cannabis use during pregnancy continues to increase. Pregnant individuals have reported using healthcare professionals and budtenders (i.e., cannabis store retailers) as resources for information on cannabis use during pregnancy and postpartum.Objectives: To determine healthcare professionals' and budtenders' perceptions of risks and benefits of perinatal cannabis use.Method: A qualitative study, using semi-structured, open-ended questions, was conducted with ten healthcare professionals (predominantly nurses; 100% women) and ten budtenders (70% women) in a state where cannabis use is legal for adults 21 years of age and older. Data were interpreted using a qualitative description methodology to identify themes. Themes were generated from participant responses (implicit and explicit). We analyzed data separately and sequentially and present linked themes across samples. Data saturation, rigor, and trustworthiness were discussed and agreed upon by the analytic team.Results: Six themes arose from the healthcare professional and budtender data: 1) Perinatal customers and patients perceive cannabis to be medicinal, 2) Supporting perinatal people who use cannabis, 3) Spectrum of perceived impacts of perinatal cannabis use, 4) Comparison to use of other substances during pregnancy, 5) Perceived limited knowledge and training about cannabis regulation and product safety, and 6) Current trends of purchase and use.Conclusion: Participants reported that perinatal patients/customers perceived cannabis to be medicinal, and highlighted non-judgmental/harm reduction strategies for engaging patients/customers. Training is needed for healthcare professionals and budtenders to assist with patient/customer discussions about perinatal cannabis use.

Abstract
INTRODUCTION This study used phenomenological qualitative research design to understand the primary psychosocial stressors American Indian (AI) women face during pregnancy-factors that may be overlooked as contributing to the community's heightened preterm birth rate-and to identify mechanisms of resilience. METHOD Using Lakota talking circles (TCs) as the data collection method, researchers collected young mothers' and tribal elders' narratives about pregnancy and parenting. Themes were derived and verified from the transcripts. RESULTS During the TCs, the women identified transgenerational/historical trauma and instability in housing, childcare, and relationships as major contributors to pregnancy and parenting stress. DISCUSSION Having overcome obstacles while bearing and raising children, AI women exhibit resilience. Participants indicated that the TCs provided support and a cultural connection, thus serving as both a data collection method and an intervention. Future work will involve using TCs to support young mothers, transmit elder wisdom, and increase resilience among AI women.

Abstract
Substance abuse is an established risk factor for crime and violence, including sexual violence. Nevertheless, the link between cannabis use and sexual offenses remains poorly understood. Cannabis use has a broad effect on sexual functioning and can have both acute and lasting adverse effects on psychological functioning, which in turn can elevate the risk of sexual offending behavior. Yet there is a scarcity of studies that have examined the link between cannabis use and sexual offending. To help fill the gap, this perspective review investigates the link between substance use and crime with a particular emphasis on cannabis use and its effects on sexual and psychological functioning. It then explores how these mechanisms may contribute to sexual offenses and recidivism, with a final discussion on how cannabis use should be conceptualized as a risk factor for sexual violence.

Abstract
Substance abuse by women of child-bearing age and fetal in utero drug exposure has increased in the number of infants born with health issues. Prenatal exposure to psychoactive substances can lead to neurological and neurodevelopmental deficits later in life. Useful data concerning the effects of psychoactive drugs on fetal neurodevelopmental status are sparse. Understanding the neurodevelopmental consequences of prenatally drug-exposed children has become a pressing global concern. The aim of this review is to gather current evidence and information on neurodevelopmental outcomes of in utero drug exposure. A literature search was performed on the PubMed, Scopus, and Google Scholar databases using the terms “psychotropic drugs”, “neurodevelopmental consequences”, “prenatal drug exposure”, and “pregnancy”. Available studies on in utero drug exposure were reviewed and found to support the idea that some degree of health issues are present in fetuses and children. Different psychoactive substances have profound neurodevelopmental consequences, such as structural brain changes, poor attention span, Down syndrome, attention deficit hyperactivity disorder, autism spectrum disorder, imbalances in neurotransmitter levels, and many structural deficits. The pervasive use of psychoactive drugs in women of child-bearing age is an important health concern. Further scientific efforts are needed to investigate the effect of prenatal exposure to psychoactive drugs on children.

Abstract
IMPORTANCE While some studies have found an association between marijuana use and adverse neonatal outcomes, results have not been consistent across all trials. OBJECTIVE To assess available data on neonatal outcomes in marijuana-exposed pregnancies. DATA SOURCES PubMed, Medline, ClinicalTrials.gov, Cochrane, Scopus, and Web of Science were searched from each database's inception until August 16, 2021. STUDY SELECTION All interventional and observational studies that included pregnant women who were exposed to marijuana compared with pregnant women who were not exposed to marijuana and that reported neonatal outcomes were included. DATA EXTRACTION AND SYNTHESIS Reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses guideline. Data were extracted by 2 authors for all outcomes, which were pooled using a random-effects model as mean difference or risk ratio (RR) and 95% CI. Data were analyzed from August through September 2021. MAIN OUTCOMES AND MEASURES All outcomes were formulated prior to data collection. Outcomes included incidence of birth weight less than 2500 g, small for gestational age (defined as less than the fifth percentile fetal weight for gestational age), rate of preterm delivery (defined as before 37 weeks' gestation), gestational age at time of delivery, birth weight, incidence of neonatal intensive care unit (NICU) admission, Apgar score at 1 minute, Apgar score at 5 minutes, incidence of an Apgar score less than 7 at 5 minutes, fetal head circumference, and fetal length. RESULTS Among 16 studies including 59 138 patients, there were significant increases in 7 adverse neonatal outcomes among women who were exposed to marijuana during pregnancy vs those who were not exposed during pregnancy. These included increased risk of birth weight less than 2500 g (RR, 2.06 [95% CI, 1.25 to 3.42]; P = .005), small for gestational age (RR, 1.61 [95% CI, 1.44 to 1.79]; P < .001), preterm delivery (RR, 1.28 [95% CI, 1.16 to 1.42]; P < .001), and NICU admission (RR, 1.38 [95% CI, 1.18 to 1.62]; P < .001), along with decreased mean birth weight (mean difference, -112.30 [95% CI, -167.19 to -57.41] g; P < .001), Apgar score at 1 minute (mean difference, -0.26 [95% CI, -0.43 to -0.09]; P = .002), and infant head circumference (mean difference, -0.34 [95% CI, -0.63 to -0.06] cm; P = .02). CONCLUSIONS AND RELEVANCE This study found that women exposed to marijuana in pregnancy were at a significantly increased risk of some adverse neonatal outcomes. These findings suggest that increasing awareness about these risks may be associated with improved outcomes.

Abstract
Objective: Little is known about women's attitudes toward cannabis use during labor. We aim to address this gap by (1) reporting on attitudes toward cannabis use during labor, including cannabis use during most recent childbirth; and (2) examining the extent to which attitudes, willingness to use cannabis during labor, and cannabis use during most recent childbirth vary across state-level cannabis policies. Methods: In Spring 2021, we recruited biological women of reproductive age (18–40 years) for an online survey. We collected sociodemographic information and asked women about their attitudes toward cannabis use during labor, willingness to use cannabis during labor, and prior cannabis use during most recent childbirth. We ran descriptive statistics and used Fisher's exact tests to examine the association between state cannabis policies and attitudes toward cannabis use during labor, including willingness to use cannabis during labor. Results: In our sample (N = 163), most women reported they would either consider using (47.85%) or previously used (3.07%) cannabis during labor. Compared with women who would not use, women who reported willingness to use or prior use of cannabis during labor were more likely to report a lower annual household income (p = 0.001) and education level (p < 0.001). Women willing to consider cannabis use were also more likely to report prenatal cannabis use (p < 0.001) and reside in a state with recreational cannabis legalization (p = 0.003). Women who would not consider using cannabis during labor were more likely to perceive one or more risks of use compared with women who would consider using cannabis during labor (90.00% vs. 72.29%, respectively; p = 0.005). In fully illegal states, 66% of women reported they would be more likely to use cannabis during labor if it were legal. Conclusions: Future research is urgently needed to guide clinical practice. To mitigate adverse health outcomes, prenatal care providers should discuss cannabis use during labor with their patients.

Abstract
OBJECTIVE To study the association between nicotine or cannabis metabolite presence in maternal urine and child neurodevelopmental outcomes. METHODS We conducted a secondary analysis of two parallel multicenter randomized controlled trials of treatment for hypothyroxinemia or subclinical hypothyroidism among pregnant individuals enrolled at 8-20 weeks of gestation. All maternal-child dyads with a maternal urine sample at enrollment and child neurodevelopmental testing were included (N=1,197). Exposure was urine samples positive for nicotine (cotinine) or cannabis 11-nor-9-carboxy-delta-9-tetrahydrocannabinol [THC-COOH]) or both metabolites. Primary outcome was child IQ at 60 months. Secondary outcomes included cognitive, motor and language, attention, behavioral and social competency, and differential skills assessments at 12, 24, 36, and 48 months. Quantile regression analysis was performed with confounder adjustment. RESULTS Of 1,197 pregnant individuals, 99 (8.3%) had positive cotinine samples and 47 (3.9%) had positive THC-COOH samples; 33 (2.8%) were positive for both. Groups differed in self-reported race and ethnicity, education, marital status, insurance, and thyroid status. Median IQ was similar between cotinine-exposed and -unexposed children (90 vs 95, adjusted difference in medians -2.47, 95% CI -6.22 to 1.29) and THC-COOH-exposed and -unexposed children (89 vs 95, adjusted difference in medians -1.35, 95% CI -7.76 to 5.05). In secondary outcome analysis, children with THC-COOH exposure compared with those unexposed had higher attention scores at 48 months of age (57 vs 49, adjusted difference in medians 6.0, 95% CI 1.11-10.89). CONCLUSIONS Neither prenatal nicotine nor cannabis exposure was associated with a difference in IQ. Cannabis exposure was associated with worse attention scores in early childhood. Longitudinal studies assessing associations between child neurodevelopmental outcomes and prenatal nicotine and cannabis exposure with a focus on timing and quantity of exposure are needed.

Abstract
BACKGROUND Cannabis use among pregnant and lactating people is increasing, despite clinical evidence showing that cannabis use may be associated with low birth weight and childhood developmental deficits. Our objective was to understand why pregnant and lactating people use cannabis and how these motivations change across perinatal stages. METHODS Using qualitative, constructivist grounded theory methodology, we conducted telephone and virtual interviews with 52 individuals from across Canada. We selected participants using maximum variation and theoretical sampling. They were eligible if they had been pregnant or lactating within the past year and had decided to continue, cease or decrease their cannabis use during the perinatal period. RESULTS We identified 3 categories of reasons that people use cannabis during pregnancy and lactation: sensation-seeking for fun and enjoyment; symptom management of chronic conditions and conditions related to pregnancy; and coping with the unpleasant, but nonpathologized, experiences of life. Before pregnancy, participants endorsed reasons for using cannabis in these 3 categories in similar proportions, with many offering multiple reasons for use. During pregnancy, reasons for use shifted primarily to symptom management. During lactation, reasons returned to resemble those expressed before pregnancy. INTERPRETATION In this study, we showed that pregnant and lactating people use cannabis for many reasons, particularly for symptom management. Reasons for cannabis use changed across reproductive stages. The dynamic nature of the reasons for use across stages speaks to participant perception of benefits and risks, and perhaps a desire to cast cannabis use during pregnancy as therapeutic because of perceived stigma.

Abstract
BACKGROUND Little is known about breastfeeding initiation and duration in the context of postpartum marijuana use and safety beliefs. RESEARCH AIMS (1) To describe characteristics of women who used marijuana postpartum; (2) to evaluate the relationship between postpartum marijuana use and breastfeeding behaviors; and 3) to assess, among women who used marijuana postpartum, how safety perceptions are associated with breastfeeding behaviors. METHODS Data from the cross-sectional Pregnancy Risk Assessment Monitoring System, a United States national governmental survey, 2017, were analyzed for participants with infants aged ≥ 12 weeks (seven states, unweighted N = 4604). Chi-square tests were used to compare characteristics and counseling for postpartum marijuana use. For participants with postpartum use, adjusted prevalence ratios (aPR) were calculated to evaluate relationships between safety perceptions and breastfeeding initiation and duration. RESULTS Overall, 5.5% (95% CI [4.6, 6.6]) of participants reported postpartum marijuana use; among these women, 47.2% (CI [37.6, 56.9]) were breastfeeding at the time of the survey. Overall, 25.7% of participants indicated that they had been advised, by their prenatal care provider, against marijuana use while breastfeeding. Breastfeeding initiation or duration did not differ by postpartum marijuana use. Among participants with postpartum use, those who perceived marijuana was safe for breastfeeding women to use were more likely to have breastfed (aPR = 1.22, CI [1.04, 1.43]) and have a breastfeeding duration > 12 weeks (aPR = 1.57, CI [1.08, 2.27]) compared to those who perceived it to be unsafe. CONCLUSIONS Understanding maternal safety beliefs and provider education about the latest evidence and guidance related to postpartum marijuana use may improve clinical care.

Woodruff K, Scott KA, Roberts SCM. Pregnant people's experiences discussing their cannabis use with prenatal care providers in a state with legalized cannabis. Drug Alcohol Depend 2021; 227:108998. [PMID: 34482037 DOI: 10.1016/j.drugalcdep.2021.108998] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Revised: 08/20/2021] [Accepted: 08/21/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND As cannabis legalization spreads, so do concerns about potential harms from use during pregnancy. Legalization may facilitate improved patient-provider interactions about cannabis use. Yet little is known about pregnant people's discussions of cannabis use with healthcare providers in an environment where recreational cannabis is legal. METHODS In May-August 2019, we conducted semi-structured in-depth interviews with 33 pregnant or postpartum people in California who used cannabis during pregnancy, and explored their discussions with healthcare providers about their cannabis use. We audio-recorded and transcribed interviews, and conducted thematic analysis using inductive and deductive methods. RESULTS Participants were diverse by age, race/ethnicity, and socio-economic position. Most reported daily cannabis use, both before and during pregnancy. Most participants did not disclose their cannabis use to their prenatal care providers, due to fears of being reported to child protective services (CPS), or fears of provider judgment. Participants reported that few providers initiated any discussions about cannabis use in pregnancy with them; some participants interpreted this omission as tacit endorsement of cannabis use in pregnancy. When participants and providers did discuss cannabis use in pregnancy, participants heard a wide range of sometimes-conflicting health messages, as well as some legal threats. CONCLUSIONS This study documents notable deficits in patient-provider interactions about cannabis. Pregnant patients' fears of being reported to CPS and separated from their children for cannabis use persist despite cannabis legalization. Providers' role as potential reporters to CPS appears to pose a significant barrier to comprehensive, compassionate counseling and education on cannabis use in pregnancy.

[PMID: 33469174 DOI: 10.1038/s41390-020-01332-2] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2020] [Revised: 12/02/2020] [Accepted: 12/05/2020] [Indexed: 01/30/2023]
Abstract
BACKGROUND Information on cannabinoids in breast milk and maternal cannabis use is limited. We quantified cannabinoids in plasma and breast milk of breastfeeding mothers and assessed cannabis use patterns. METHODS This is a prospective study at a university hospital in a state with legal medical and recreational cannabis. Breast milk and plasma samples along with survey data were collected from volunteers using cannabis in the last 48 h at 2 weeks and 2 months postpartum. RESULTS Twenty subjects were enrolled. Median age (IQR) was 27 (24-34) years. Median (IQR) instances of cannabis use in the last 7 days were visit 1: 17 (6-29) and visit 2: 23 (15-45). Median (IQR) tetrahydrocannabinol (THC) concentrations were: plasma 3.7 ng/ml (0.8-56.8) and breast milk 27.5 ng/ml (0.8-190.5). Median (IQR) cannabidiol (CBD) concentrations were: plasma 0.6 ng/ml (0.5-6.4) and breast milk 1.2 ng/ml (0.5-17.0). Median (IQR) THC M/P: 7.0 (1.8-34.6) and CBD M/P: 2.6. Median breast milk THC concentration increased from visit 1 to visit 2 by 30.2 ng/ml (95% CI 3.05-69.3 ng/ml). CONCLUSIONS THC and CBD accumulate in breast milk. Breastfeeding mothers used cannabis frequently and increased use in the early postpartum period. Research on the effects of infant exposure to cannabinoids in breast milk is urgently needed. IMPACT Cannabis use is increasing in the general population and many nursing mothers use cannabis. THC has been previously detected in breast milk but little is known on how it concentrates relative to plasma. Data on cannabinoids other than THC, reasons for cannabis use, and patterns of use in breastfeeding women are also limited. We detected THC and CBD in breast milk. Both concentrate in breast milk relative to plasma. We showed that breastfeeding mothers increased cannabis use in the weeks after childbirth. Further research is needed to evaluate infant exposure to cannabinoids via breast milk and effects on infant health.

Abstract
BACKGROUND The prevalence of opioid use disorder has increased across the United States, but the rural population of Appalachia has been disproportionately impacted. Concurrently, the slow, but steady progress in the legalization of marijuana may be affecting perception of marijuana use in pregnancy. However, marijuana use in pregnancy has been associated with adverse perinatal outcomes. Concomitant use of opioids and marijuana in pregnancy has not been evaluated. OBJECTIVE The primary aim of the study was to evaluate the association between confirmed marijuana use in late pregnancy and preterm birth in opioid-exposed pregnancies. METHODOLOGY A retrospective chart review was conducted that included all births from July 2011 to June 2016 from 6 delivery hospitals in South-Central Appalachia. Out of 18,732 births, 2368 singleton pregnancies indicated opioid use and met remaining inclusion criteria, with 108 of these mothers testing positive for marijuana at delivery. Independent sample t-test and Chi-Square analyses compared marijuana and non-marijuana exposed groups on maternal and neonatal outcomes. Regression analyses controlled for confounding variables in predicting neonatal abstinence syndrome (NAS), NICU admission, preterm birth, small for gestational age, and low birth weight outcomes as shown in Table 1. RESULTS Neonates born to marijuana-positive women in opioid-exposed pregnancy were more likely to be born preterm, small for gestational age, have low birth weight, and be admitted to NICU. After statistically controlling for parity, marital status, tobacco and benzodiazepine use, preterm birth and low birth weight remained statistically significant with aOR of 2.35 (1.30-4.24) and 2.01 (1.18-3.44), respectively. CONCLUSIONS Maternal use of marijuana in any opioid-exposed pregnancy may increase risk of preterm birth and low-birth weight infants. Prospective studies need to examine the dose and timing of marijuana and opioid use in pregnancy to better delineate perinatal effects. Nonetheless, pregnant women using opioids, including recommended medication assisted treatment for opioid use disorder, should be educated about the risks of concurrent marijuana use during pregnancy and may need to be counseled to abstain from marijuana use during pregnancy for an optimal outcome.

Abstract
Up to 20% of pregnant women ages 18-24 consume cannabis during pregnancy. Moreover, clinical studies indicate that cannabis consumption during pregnancy leads to fetal growth restriction (FGR), which is associated with an increased risk of obesity, type II diabetes (T2D), and cardiovascular disease in the offspring. This is of great concern considering that the concentration of Δ9- tetrahydrocannabinol (Δ9-THC), a major psychoactive component of cannabis, has doubled over the last decade and can readily cross the placenta and enter fetal circulation, with the potential to negatively impact fetal development via the endocannabinoid (eCB) system. Cannabis exposure in utero could also lead to FGR via placental insufficiency. In this review, we aim to examine current pre-clinical and clinical findings on the direct effects of exposure to cannabis and its constituents on fetal development as well as indirect effects, namely placental insufficiency, on postnatal metabolic diseases.

Abstract
INTRODUCTION Passage of cannabis laws may impact cannabis use and the use of other substances. The suggested association is of particular concern in pregnant women where exposure to substances can cause harm to both the pregnant woman and fetus. The present study contributes to the minimal literature on factors associated with cannabis use during the preconception, prenatal, and postpartum periods including state legalization status, concurrent use of tobacco and e-cigarettes and adequacy of prenatal care. METHODS We conducted a cross-sectional analysis using combined survey data from the 2016-2018 Pregnancy Risk Assessment Monitoring System (PRAMS) collected from 36,391 women. Logistic regression was used to estimate the impact of state-legalization, adequacy of prenatal care, and other substance use on cannabis use during the preconception, prenatal, and post-partum periods. RESULTS In the preconception model, residence in a recreationally legal state (OR: 2.37; 95% CI, 2.04-2.75) or medically legal state (OR:3.32; 95% CI, 2.90-3.80) compared to a non-legal state was associated with higher odds of cannabis use. In the prenatal model, residence in a recreationally legal state was associated with higher odds of cannabis use (OR: 1.51; 95% CI, 1.29-1.79) whereas there was no association with residence in a medically legal state. Tobacco use including e-cigarettes and moderate prenatal alcohol use were also significantly associated with cannabis use. CONCLUSION Recreational cannabis legalization is associated with the use of cannabis prior to, during, and after pregnancy. Renewed clinical and policy efforts may be warranted to update prenatal substance use prevention programs, educational campaigns, and provider education as cannabis legalization evolves.

Abstract
Cannabis use during pregnancy has continued to rise, particularly in developed countries, as a result of the trend towards legalization and lack of consistent, evidence-based knowledge on the matter. While there is conflicting data regarding whether cannabis use during pregnancy leads to adverse outcomes such as stillbirth, preterm birth, low birthweight, or increased admission to neonatal intensive care units, investigations into long-term effects on the offspring’s health are limited. Historically, studies have focused on the neurobehavioral effects of prenatal cannabis exposure on the offspring. The effects of cannabis on other physiological aspects of the developing fetus have received less attention. Importantly, our knowledge about cannabinoid signaling in the placenta is also limited. The endocannabinoid system (ECS) is present at early stages of development and represents a potential target for exogenous cannabinoids in utero. The ECS is expressed in a broad range of tissues and influences a spectrum of cellular functions. The aim of this review is to explore the current evidence surrounding the effects of prenatal exposure to cannabinoids and the role of the ECS in the placenta and the developing fetus.

Abstract
BACKGROUND Pregnant women with a substance-related diagnosis, such as alcohol use disorder, are a vulnerable population who may be experiencing disproportionate rates of severe maternal morbidity, such as hemorrhage and eclampsia, compared to pregnant women without a substance-related diagnosis. METHODS This retrospective cross-sectional study reviewed electronic health record data on women (ages 18-44 years) who delivered a single live or stillbirth at ≥ 20 weeks of gestation from March 1st , 2016-August 30th , 2019. Women with and without a substance-related diagnosis were matched on key demographic characteristics such as age at a 1:1 ratio. Adjusting for these covariates, odds ratios and 95% confidence intervals were calculated. RESULTS There were a total of 10,125 deliveries that met the eligibility criteria for this study. In the matched cohort of 1,346 deliveries, 673 (50.0%) had a substance-related diagnosis and 94 (7.0%) had severe maternal morbidity. The most common indicators in those with a substance-related diagnosis included hysterectomy (17.7%), eclampsia (15.8%), air and thrombotic embolism (11.1%), and conversion of cardiac rhythm (11.1%). Having a substance-related diagnosis was associated with severe maternal morbidity (adjusted odds ratio = 1.81 [95% CI, 1.14-2.88], p-value = 0.0126). In the independent matched cohorts by substance type, an alcohol-related diagnosis was significantly associated with severe maternal morbidity (adjusted odds ratio = 3.07 [95% CI, 1.58-5.95], p-value = 0.0009), the patterns for stimulant- and nicotine-related diagnoses were not as well resolved with SMM, and opioid- and cannabis-related diagnoses were not associated with SMM. CONCLUSION Our data showed that an alcohol-related diagnosis had the lowest prevalence and the highest odds of severe maternal morbidity compared to any other substance assessed in this study. The results from this study reinforce the need to identify an alcohol related-diagnosis in pregnant women early to minimize potential harm through intervention and treatment.

Abstract
Recent surveys have shown increased use of marijuana during the perinatal period, possibly linked to increased legalization in many countries. Available information on the association between marijuana exposure and the effects on growth and development, as well as brain structure and function of the fetus, is growing but has not been uniform. Interpretation of these data is often challenging because of the influence of confounding factors and the sociodemographic variabilities in the study subjects. In this review, we present a synthesis of current information on the epidemiology and effects of marijuana use during pregnancy and evaluate the evidence for the immediate and long-term effects on affected neonates. We also describe the current knowledge and implications of breastfeeding and marijuana use and summarize selected current references about this practice. Finally, we provide the rationale for additional biological and population-based investigations to determine the various fetal outcomes of in-utero marijuana exposure that may assist in the establishment of prevention measures and applicable public health policies in the future.

Abstract
BACKGROUND Cannabis use and cannabis use disorders are increasing in prevalence, including among pregnant women. The objective was to evaluate the association of a cannabis-related diagnosis (CRD) in pregnancy and adverse maternal and infant outcomes. METHODS We queried an administrative birth cohort of singleton deliveries in California between 2011-2017 linked to maternal and infant hospital discharge records. We classified pregnancies with CRD from International Classification of Disease codes. We identified nicotine and other substance-related diagnoses (SRD) in the same manner. Outcomes of interest included maternal (hypertensive disorders) and infant (prematurity, small for gestational age, NICU admission, major structural malformations) adverse outcomes. RESULTS From 3,067,069 pregnancies resulting in live births, 29,112 (1.0 %) had a CRD. CRD was associated with an increased risk of all outcomes studied; the strongest risks observed were for very preterm birth (aRR 1.4, 95 % CI 1.3, 1.6) and small for gestational age (aRR 1.4, 95 % CI 1.3, 1.4). When analyzed with or without co-exposure diagnoses, CRD alone conferred increased risk for all outcomes compared to no use. The strongest effects were seen for CRD with other SRD (preterm birth aRR 2.3, 95 % CI 2.2, 2.5; very preterm birth aRR 2.6, 95 % CI 2.3, 3.0; gastrointestinal malformations aRR 2.0, 95 % CI 1.6, 2.6). The findings were generally robust to unmeasured confounding and misclassification analyses. CONCLUSIONS CRD in pregnancy was associated with increased risk of adverse maternal and infant outcomes. Providing education and effective treatment for women with a CRD during prenatal care may improve maternal and infant health.

Abstract
OBJECTIVE To determine the dose-dependent effect of contemporary marijuana exposure on female menstrual cyclicity and reproductive endocrine physiology in a nonhuman primate model. DESIGN Research animal study. SETTING Research institute environment. ANIMALS Adult female rhesus macaques (6-12 years of age; n = 8). INTERVENTIONS Daily delta-9-tetrahydrocannabinol (THC) edible at medically and recreationally relevant contemporary doses. MAIN OUTCOME MEASURES Menstrual cycle length (MCL), anti-Müllerian hormone, prolactin, basal follicle-stimulating hormone (FSH), estradiol (E2) and progesterone, luteinizing hormone (LH), and thyroid-stimulating hormone. RESULTS The average before THC weight was 6.9 kg (standard deviation, 0.8), and at the highest THC dosing, the average weight was 7.2 kg (standard deviation, 0.8). With increasing THC dosing, MCL and FSH concentrations increased, while basal E2 concentration was stable. The average MCL concentration increased 4.0 days for each mg/7 kg/day of THC (95% CI, 1.4-6.6 days). Follicle-stimulating hormone concentration increased significantly with increasing THC dose, 0.34 ng/mL for each mg/7 kg/day of THC (95% CI, 0.14-0.57 ng/mL). No significant trends were observed between THC dosing and average basal progesterone, anti-Müllerian hormone, prolactin, LH, or thyroid-stimulating hormone concentrations. CONCLUSIONS In rhesus macaques, a dose response toward increased MCL and basal FSH concentrations but plateau of basal E2 and LH concentrations was observed with increasing THC dosing, suggesting ovulatory dysfunction. Further studies are needed to determine the effects of a longer duration of exposure and whether the significant increase in MCL and FSH concentrations results in reduced fecundity.
