Stevens MWR, Cooper M, Cusack L, Ali RL, Holmwood C, Briley AL. Screening and early intervention for substance use during pregnancy: A retrospective case note review of antenatal care records. Drug Alcohol Rev 2024. [PMID: 39138132 DOI: 10.1111/dar.13927] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2024] [Revised: 07/23/2024] [Accepted: 07/24/2024] [Indexed: 08/15/2024]
Abstract
INTRODUCTION Screening for substance use during pregnancy is critical for enhancing maternal health and perinatal outcomes. However, disparities persist in screening and intervention rates within maternity services. This retrospective case note review explored contemporaneous practices around screening and interventions for substance use among pregnant women during routine antenatal care. METHODS A random sample of 100 sets of maternity records were reviewed. Eligible cases included any woman attending initial pregnancy assessments at one of two South Australian metropolitan Hospital-based antenatal clinics, from July 2019-September 2020. Screening rates for past and current alcohol, tobacco and other substance use were identified and compared with data from a subset of a nationally representative survey. Intervention details and referral pathways were also assessed. RESULTS The final sample of eligible cases (n = 93) demonstrated prioritisation of screening for current use, over past use, across all substances (p < 0.001). Screening was most likely for tobacco and least likely for e-cigarettes (p < 0.001). Significant underreporting of past use compared with the benchmark was identified for all substances (except tobacco, p = 0.224). Interventions typically involved written resources, which were usually declined by clients. DISCUSSION AND CONCLUSIONS Despite longstanding recommendations, screening and intervention practices for substance use appear inconsistent. With the recent emergence of vaping, no evidence of updated approaches to identifying e-cigarette consumption in pregnant women was found. Several opportunities for enhancing routine screening and intervention practices within antenatal clinics were identified, and will inform the development of policy directives, targeted training modules, and other resources for health professionals working in these services.

Abstract
The use of alprazolam in pregnancy can adversely affect maternal and neonatal health. This study examined neonatal outcomes following exposure to alprazolam in pregnancy. Women prescribed alprazolam during pregnancy (n = 48) between 2014 and 2018 were identified from routinely-collected state administrative prescribing records and perinatal data. Two comparison groups of women; 1) prescribed alprazolam outside of pregnancy (n = 96) and 2) women never prescribed alprazolam (n = 96) were also identified. The health of women and their children was examined using administrative hospital, mortality and perinatal data and compared to the comparison groups using generalized linear models. Prenatal alprazolam exposure was not associated with a reduction in average birth weight or gestational age. However, neonates prenatally exposed to alprazolam were more likely be classified as having low birth weight for gestational age compared with alprazolam comparison group (OR: 4.46, 95% CI: 1.54-12.95) and the non-alprazolam comparison group (OR: 3.27, 95% CI: 1.22-8.79). There were no cases of perinatal mortality or floppy baby syndrome in alprazolam-exposed neonates. While the use of alprazolam during pregnancy was not associated with an increased risk of severe adverse neonatal outcomes (e.g. perinatal mortality), it was associated with neonates being born with a low birth weight for gestational age.

Abstract
Introduction Cannabis use among pregnant women has increased over time. Therefore, there is a great public health need to understand the consequences of in utero cannabis exposure. While several meta-analyses and reviews have summarized the evidence of in utero cannabis exposure on adverse obstetric outcomes (e.g., low birth weight and preterm birth) and long-term offspring development, there has not been a focus on in utero cannabis exposure and risk for structural birth defects. Methods We conducted a systematic review using PRISMA guidelines to evaluate the association between in utero cannabis exposure and structural birth defects. Results We identified 20 articles to include in our review and focused on interpreting findings from the 12 that adjusted for potential confounders. We report findings by seven organ systems. Within the 12 articles, four reported on cardiac malformations, three reported on central nervous system malformations, one reported on eye malformations, three reported on gastrointestinal malformations, one reported on genitourinary malformations, one reported on musculoskeletal malformations, and two reported on orofacial malformations. Discussion Findings on associations between in utero cannabis exposure and birth defects reported in more than two articles were mixed (i.e., findings for cardiac, gastrointestinal, central nervous system malformations). Findings for associations between in utero cannabis exposure and birth defects reported in two articles (i.e., orofacial malformations) or in a single article (eye, genitourinary, and musculoskeletal) suggested that cannabis exposure was not associated with these types of malformations, but strong conclusions cannot be drawn from such sparce research. We review the limitations and gaps in the existing literature and call for more research to rigorously evaluate associations between in utero cannabis exposure and structural birth defects. Systematic Review Registration identifier CRD42022308130.

Early mortality among aboriginal and non-aboriginal women who had a preterm birth in Western Australia: A population-based cohort study. Paediatr Perinat Epidemiol 2023; 37:31-44. [PMID: 36331146 PMCID: PMC10946802 DOI: 10.1111/ppe.12929] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Revised: 09/19/2022] [Accepted: 09/21/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND Having a preterm (<37 weeks' gestation) birth may increase a woman's risk of early mortality. Aboriginal and Torres Strait Islander (hereafter Aboriginal) women have higher preterm birth and mortality rates compared with other Australian women. OBJECTIVES We investigated whether a history of having a preterm birth was associated with early mortality in women and whether these associations differed by Aboriginal status. METHODS This retrospective cohort study used population-based perinatal records of women who had a singleton birth between 1980 and 2015 in Western Australia linked to Death Registry data until June 2018. The primary and secondary outcomes were all-cause and cause-specific mortality respectively. After stratification by Aboriginal status, rate differences were calculated, and Cox proportional hazard regression was used to estimate adjusted hazard ratios (HR) and 95% confidence intervals (CI) for all-cause and cause-specific mortality. RESULTS There were 20,244 Aboriginal mothers (1349 deaths) and 457,357 non-Aboriginal mothers (7646 deaths) with 8.6 million person-years of follow-up. The all-cause mortality rates for Aboriginal mothers who had preterm births and term births were 529.5 and 344.0 (rate difference 185.5, 95% CI 135.5, 238.5) per 100,000 person-years respectively. Among non-Aboriginal mothers, the corresponding figures were 125.5 and 88.6 (rate difference 37.0, 95% CI 29.4, 44.9) per 100,000 person-years. The HR for all-cause mortality for Aboriginal and non-Aboriginal mothers associated with preterm birth were 1.48 (95% CI 1.32, 1.66) and 1.35 (95% CI 1.26, 1.44), respectively, compared with term birth. Compared with mothers who had term births, mothers of preterm births had higher relative risks of mortality from diabetes, cardiovascular, digestive and external causes. CONCLUSIONS Both Aboriginal and non-Aboriginal women who had a preterm birth had a moderately increased risk of mortality up to 38 years after the birth, reinforcing the importance of primary prevention and ongoing screening.

Associations of Mental Health Measures and Retention in a Community-Based Perinatal Care Recovery Support Program for Women of Childbearing Age With Substance Use Disorder. J Dual Diagn 2022; 18:211-219.

Abstract
Objective: This research was undertaken to evaluate factors related to program retention among participants in a community-based peer recovery program for women of childbearing age with a history of substance use disorder. Methods: In all, 184 women of childbearing age with a history of substance use disorder were enrolled in a community-based peer recovery program. Half of the participants were pregnant or postpartum. The outcome of interest was retention in the program as measured at 2 and 6 months. Participants were paired with a peer recovery coach (PRC). PRCs were women with a personal history of substance use disorder who assisted with healthcare system navigation, facilitated access to local resources, and provided advice and emotional support. All PRCs were also licensed perinatal community health workers. Independent variables included gestational status, depression, anxiety, type and frequency of substance use, childhood trauma, abuse, readiness for treatment, and attachment patterns. Results: Anxiety was found to be a key factor associated with retention. Moderate anxiety was associated with higher rates of retention compared to normal to mild anxiety. Severe anxiety was associated with lower rates of retention compared to normal to mild anxiety. Attrition was highest in the first 2 months. Conclusions: Early integration with mental health services to address severe anxiety symptoms could potentially improve retention in substance use disorder recovery programs, thereby improving outcomes. More research is needed regarding severe anxiety and care-avoidant behaviors, particularly among women of childbearing age.

Abstract
BACKGROUND Neonatal abstinence syndrome (NAS) due to opioid withdrawal may result in disruption of the mother-infant relationship, sleep-wake abnormalities, feeding difficulties, weight loss, seizures and neurodevelopmental problems. OBJECTIVES To assess the effectiveness and safety of using an opioid for treatment of NAS due to withdrawal from opioids in newborn infants. SEARCH METHODS We ran an updated search on 17 September 2020 in CENTRAL via Cochrane Register of Studies Web and MEDLINE via Ovid. We also searched clinical trials databases, conference proceedings and the reference lists of retrieved articles for eligible trials. SELECTION CRITERIA We included randomised controlled trials (RCTs), quasi- and cluster-RCTs which enrolled infants born to mothers with opioid dependence and who were experiencing NAS requiring treatment with an opioid. DATA COLLECTION AND ANALYSIS Three review authors independently assessed trial eligibility and risk of bias, and independently extracted data. We used the GRADE approach to assess the certainty of evidence. MAIN RESULTS We included 16 trials (1110 infants) with NAS secondary to maternal opioid use in pregnancy. Seven studies at low risk of bias were included in sensitivity analysis. Opioid versus no treatment / usual care: a single trial (80 infants) of morphine and supportive care versus supportive care alone reported no difference in treatment failure (risk ratio (RR) 1.29, 95% confidence interval (CI) 0.41 to 4.07; very low certainty evidence). No infant had a seizure. The trial did not report mortality, neurodevelopmental disability and adverse events. Morphine increased days hospitalisation (mean difference (MD) 15.00, 95% CI 8.86 to 21.14; very low certainty evidence) and treatment (MD 12.50, 95% CI 7.52 to 17.48; very low certainty evidence), but decreased days to regain birthweight (MD -2.80, 95% CI -5.33 to -0.27) and duration (minutes) of supportive care each day (MD -197.20, 95% CI -274.15 to -120.25). Morphine versus methadone: there was no difference in treatment failure (RR 1.59, 95% CI 0.95 to 2.67; 2 studies, 147 infants; low certainty evidence). Seizures, neonatal or infant mortality and neurodevelopmental disability were not reported. A single study reported no difference in days hospitalisation (MD 1.40, 95% CI -3.08 to 5.88; 116 infants; low certainty evidence), whereas data from two studies found an increase in days treatment (MD 2.71, 95% CI 0.22 to 5.21; 147 infants; low certainty) for infants treated with morphine. A single study reported no difference in breastfeeding, adverse events, or out of home placement. Morphine versus sublingual buprenorphine: there was no difference in treatment failure (RR 0.79, 95% CI 0.36 to 1.74; 3 studies, 113 infants; very low certainty evidence). Neonatal or infant mortality and neurodevelopmental disability were not reported. There was moderate certainty evidence of an increase in days hospitalisation (MD 11.45, 95% CI 5.89 to 17.01; 3 studies, 113 infants), and days treatment (MD 12.79, 95% CI 7.57 to 18.00; 3 studies, 112 infants) for infants treated with morphine. A single adverse event (seizure) was reported in infants exposed to buprenorphine. Morphine versus diluted tincture of opium (DTO): a single study (33 infants) reported no difference in days hospitalisation, days treatment or weight gain (low certainty evidence). Opioid versus clonidine: a single study (31 infants) reported no infant with treatment failure in either group. This study did not report seizures, neonatal or infant mortality and neurodevelopmental disability. There was low certainty evidence for no difference in days hospitalisation or days treatment. This study did not report adverse events. Opioid versus diazepam: there was a reduction in treatment failure from use of an opioid (RR 0.43, 95% CI 0.23 to 0.80; 2 studies, 86 infants; low certainty evidence). Seizures, neonatal or infant mortality and neurodevelopmental disability were not reported. A single study of 34 infants comparing methadone versus diazepam reported no difference in days hospitalisation or days treatment (very low certainty evidence). Adverse events were not reported. Opioid versus phenobarbital: there was a reduction in treatment failure from use of an opioid (RR 0.51, 95% CI 0.35 to 0.74; 6 studies, 458 infants; moderate certainty evidence). Subgroup analysis found a reduction in treatment failure in trials titrating morphine to ≧ 0.5 mg/kg/day (RR 0.21, 95% CI 0.10 to 0.45; 3 studies, 230 infants), whereas a single study using morphine < 0.5 mg/kg/day reported no difference compared to use of phenobarbital (subgroup difference P = 0.05). Neonatal or infant mortality and neurodevelopmental disability were not reported. A single study (111 infants) of paregoric versus phenobarbital reported seven infants with seizures in the phenobarbital group, whereas no seizures were reported in two studies (170 infants) comparing morphine to phenobarbital. There was no difference in days hospitalisation or days treatment. A single study (96 infants) reported no adverse events in either group. Opioid versus chlorpromazine: there was a reduction in treatment failure from use of morphine versus chlorpromazine (RR 0.08, 95% CI 0.01 to 0.62; 1 study, 90 infants; moderate certainty evidence). No seizures were reported in either group. There was low certainty evidence for no difference in days treatment. This trial reported no adverse events in either group. None of the included studies reported time to control of NAS. Data for duration and severity of NAS were limited, and we were unable to use these data in quantitative synthesis. AUTHORS' CONCLUSIONS Compared to supportive care alone, the addition of an opioid may increase duration of hospitalisation and treatment, but may reduce days to regain birthweight and the duration of supportive care each day. Use of an opioid may reduce treatment failure compared to phenobarbital, diazepam or chlorpromazine. Use of an opioid may have little or no effect on duration of hospitalisation or treatment compared to use of phenobarbital, diazepam or chlorpromazine. The type of opioid used may have little or no effect on the treatment failure rate. Use of buprenorphine probably reduces duration of hospitalisation and treatment compared to morphine, but there are no data for time to control NAS with buprenorphine, and insufficient evidence to determine safety. There is insufficient evidence to determine the effectiveness and safety of clonidine.

Abstract
OBJECTIVES The prevalence of drug use is at alarmingly high levels in the United States. Of particular concern is prenatal drug use, which exposes the underdeveloped organ systems of the fetus to harsh chemicals. Identifying factors associated with illicit drug use during pregnancy is critical to identify and treat at-risk pregnant women and improve maternal and infant health outcomes. The goal of this study was to examine the association between unmet mental health care needs and substance use during pregnancy. METHODS The present cross-sectional study analyzed secondary data from the 2002 to 2014 National Survey on Drug Use and Health (n = 10,516). The main outcome of interest was self-reported illicit drug use in the last 30 days. The independent variable was unmet mental health care needs in the last 12 months. RESULTS Overall, 6.4% of the participants reported a history of unmet mental health care needs and 4.5% used a substance during pregnancy. The odds of illicit drug use during pregnancy were higher among women who had an unmet mental health care needs compared to women without a history of unmet mental health care needs, multivariable-adjusted odds ratio (95% CI) 4.06 (3.01 to 5.48; P < 0.001). The observed association between unmet mental health care needs and illicit drug use persisted in subgroup analyses by age, race/ethnicity and education. CONCLUSION In a nationally representative cross-sectional sample of pregnant women, having unmet mental health care needs was positively associated with illicit drug use during pregnancy after adjusting for potential confounders.

Abstract
BACKGROUND Neonatal abstinence syndrome (NAS) due to opioid withdrawal may result in disruption of the mother-infant relationship, sleep-wake abnormalities, feeding difficulties, weight loss, seizures and neurodevelopmental problems. OBJECTIVES To assess the effectiveness and safety of using a sedative versus control (placebo, usual treatment or non-pharmacological treatment) for NAS due to withdrawal from opioids and determine which type of sedative is most effective and safe for NAS due to withdrawal from opioids. SEARCH METHODS We ran an updated search on 17 September 2020 in CENTRAL via CRS Web and MEDLINE via Ovid. We searched clinical trials databases, conference proceedings and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. SELECTION CRITERIA We included trials enrolling infants with NAS born to mothers with an opioid dependence with more than 80% follow-up and using randomised, quasi-randomised and cluster-randomised allocation to sedative or control. DATA COLLECTION AND ANALYSIS Three review authors assessed trial eligibility and risk of bias, and independently extracted data. We used the GRADE approach to assess the certainty of the evidence. MAIN RESULTS We included 10 trials (581 infants) with NAS secondary to maternal opioid use in pregnancy. There were multiple comparisons of different sedatives and regimens. There were limited data available for use in sensitivity analysis of studies at low risk of bias. Phenobarbital versus supportive care: one study reported there may be little or no difference in treatment failure with phenobarbital and supportive care versus supportive care alone (risk ratio (RR) 2.73, 95% confidence interval (CI) 0.94 to 7.94; 62 participants; very low-certainty evidence). No infant had a clinical seizure. The study did not report mortality, neurodevelopmental disability and adverse events. There may be an increase in days' hospitalisation and treatment from use of phenobarbital (hospitalisation: mean difference (MD) 20.80, 95% CI 13.64 to 27.96; treatment: MD 17.90, 95% CI 11.98 to 23.82; both 62 participants; very low-certainty evidence). Phenobarbital versus diazepam: there may be a reduction in treatment failure with phenobarbital versus diazepam (RR 0.39, 95% CI 0.24 to 0.62; 139 participants; 2 studies; low-certainty evidence). The studies did not report mortality, neurodevelopmental disability and adverse events. One study reported there may be little or no difference in days' hospitalisation and treatment (hospitalisation: MD 3.89, 95% CI -1.20 to 8.98; 32 participants; treatment: MD 4.30, 95% CI -0.73 to 9.33; 31 participants; both low-certainty evidence). Phenobarbital versus chlorpromazine: there may be a reduction in treatment failure with phenobarbital versus chlorpromazine (RR 0.55, 95% CI 0.33 to 0.92; 138 participants; 2 studies; very low-certainty evidence), and no infant had a seizure. The studies did not report mortality and neurodevelopmental disability. One study reported there may be little or no difference in days' hospitalisation (MD 7.00, 95% CI -3.51 to 17.51; 87 participants; low-certainty evidence) and 0/100 infants had an adverse event. Phenobarbital and opioid versus opioid alone: one study reported no infants with treatment failure and no clinical seizures in either group (low-certainty evidence). The study did not report mortality, neurodevelopmental disability and adverse events. One study reported there may be a reduction in days' hospitalisation for infants treated with phenobarbital and opioid (MD -43.50, 95% CI -59.18 to -27.82; 20 participants; low-certainty evidence). Clonidine and opioid versus opioid alone: one study reported there may be little or no difference in treatment failure with clonidine and dilute tincture of opium (DTO) versus DTO alone (RR 0.09, 95% CI 0.01 to 1.59; 80 participants; very low-certainty evidence). All five infants with treatment failure were in the DTO group. There may be little or no difference in seizures (RR 0.14, 95% CI 0.01 to 2.68; 80 participants; very low-certainty evidence). All three infants with seizures were in the DTO group. There may be little or no difference in mortality after discharge (RR 7.00, 95% CI 0.37 to 131.28; 80 participants; very low-certainty evidence). All three deaths were in the clonidine and DTO group. The study did not report neurodevelopmental disability. There may be little or no difference in days' treatment (MD -4.00, 95% CI -8.33 to 0.33; 80 participants; very low-certainty evidence). One adverse event occurred in the clonidine and DTO group. There may be little or no difference in rebound NAS after stopping treatment, although all seven cases were in the clonidine and DTO group. Clonidine and opioid versus phenobarbital and opioid: there may be little or no difference in treatment failure (RR 2.27, 95% CI 0.98 to 5.25; 2 studies, 93 participants; very low-certainty evidence). One study reported one infant in the clonidine and morphine group had a seizure, and there were no infant mortalities. The studies did not report neurodevelopmental disability. There may be an increase in days' hospitalisation and days' treatment with clonidine and opioid versus phenobarbital and opioid(hospitalisation: MD 7.13, 95% CI 6.38 to 7.88; treatment: MD 7.57, 95% CI 3.97 to 11.17; both 2 studies, 91 participants; low-certainty evidence). There may be little or no difference in adverse events (RR 1.55, 95% CI 0.44 to 5.40; 2 studies, 93 participants; very low-certainty evidence). However, there was oversedation only in the phenobarbital and morphine group; and hypotension, rebound hypertension and rebound NAS only in the clonidine and morphine group. AUTHORS' CONCLUSIONS There is very low-certainty evidence that phenobarbital increases duration of hospitalisation and treatment, but reduces days to regain birthweight and duration of supportive care each day compared to supportive care alone. There is low-certainty evidence that phenobarbital reduces treatment failure compared to diazepam and very low-certainty evidence that phenobarbital reduces treatment failure compared to chlorpromazine. There is low-certainty evidence of an increase in days' hospitalisation and days' treatment with clonidine and opioid compared to phenobarbital and opioid. There are insufficient data to determine the safety and incidence of adverse events for infants treated with combinations of opioids and sedatives including phenobarbital and clonidine.

Abstract
Background: Exposure to adverse childhood experiences (ACEs) is a risk factor for maternal substance use in pregnancy, however, mechanisms by which maternal ACEs may influence substance use in pregnancy have not been fully explored. The current study examines the association between maternal ACEs and substance use in pregnancy (i.e., alcohol, smoking, and drug use) and explores mediating pathways. Methods: A community sample of 1,994 women as part of the All Our Families Cohort were recruited in pregnancy in Calgary, Canada, between 2008 and 2011. Women provided retrospective reports of ACE exposure before age 18 as well as reports of demographic information, substance use (i.e., moderate-to-high alcohol use, any smoking, or any drug use), a previous history of substance use difficulties, and depressive symptoms during pregnancy. Path analyses were used to examine maternal income, education, depression, and previous substance use as mediating variables. Results: There were significant indirect associations between maternal ACEs and maternal substance use in pregnancy via maternal education (β = 0.05, p < 0.001), previous substance use (β = 0.01, p = 0.001), and depression (β = 0.02, p = 0.02). The direct effect of maternal ACEs on maternal substance in pregnancy remained significant after accounting for the indirect effects (β = 0.22, 95% CI = 0.15-0.29, p < 0.001). Conclusions: Exposure to adversity in childhood can lead to socioeconomic and mental health difficulties that increase risk for substance use in pregnancy. Addressing these difficulties before pregnancy may help to reduce the potential for substance use in pregnancy.

Abstract
Substance use in pregnancy, including alcohol use, drug use, or smoking, is associated with poor health outcomes for both the mother and her unborn child. Building on previous research that has examined the cumulative impact of Adverse Childhood Experiences (ACEs) on maternal binge drinking and alcohol use in pregnancy, the current study sought to examine the association between maternal ACEs and substance use in pregnancy more broadly, including alcohol use, binge drinking, smoking, and drug use. Furthermore, we also examined how different adversity subtypes, including sexual abuse, family violence (physical abuse, emotional abuse), and household dysfunction, differentially predict maternal substance use behavior. A sample of 1994 women were recruited between 2008 and 2011 from a community-based pregnancy cohort in Calgary, Canada. Self-reported information on exposure to ACEs prior to the age of 18 years and maternal substance usewere collected. Examining ACE subtypes, medium effects were observed for the role of household-dysfunction on binge drinking, drug use, and smoking in pregnancy, while only small effects were observed for family violence on binge drinking, drug use, and smoking. There were no significant effects for sexual abuse after controlling for covariates. A dose-response association between the number of ACEs and substance use in pregnancy was also demonstrated. Increased support prior to, and in pregnancy, particularly for women with a history of childhood adversity, is needed to reduce substance use behaviors in pregnancy.

Abstract
OBJECTIVE To investigate behavioural and social characteristics of women who experienced a late stillbirth compared with women with ongoing live pregnancies at similar gestation. DESIGN Case-control study. SETTING 41 maternity units in the UK. POPULATION Women who had a stillbirth ≥28 weeks' gestation (n = 287) and women with an ongoing pregnancy at the time of interview (n = 714). METHODS Data were collected using an interviewer-administered questionnaire which included questions regarding women's behaviours (e.g. alcohol intake and household smoke exposure) and social characteristics (e.g. ethnicity, employment, housing). Stress was measured by the 10-item Perceived Stress Scale. MAIN OUTCOME MEASURE Late stillbirth. RESULTS Multivariable analysis adjusting for co-existing social and behavioural factors showed women living in the most deprived quintile had an increased risk of stillbirth compared with the least deprived quintile (adjusted odds ratio [aOR] 3.16; 95% CI 1.47-6.77). There was an increased risk of late stillbirth associated with unemployment (aOR 2.32; 95% CI 1.00-5.38) and women who declined to answer the question about domestic abuse (aOR 4.12; 95% CI 2.49-6.81). A greater number of antenatal visits than recommended was associated with a reduction in stillbirth (aOR 0.26; 95% CI 0.16-0.42). CONCLUSIONS This study demonstrates associations between late stillbirth and socio-economic deprivation, perceived stress and domestic abuse, highlighting the need for strategies to prevent stillbirth to extend beyond maternity care. Enhanced antenatal care may be able to mitigate some of the increased risk of stillbirth. TWEETABLE ABSTRACT Deprivation, unemployment, social stress & declining to answer about domestic abuse increase risk of #stillbirth after 28 weeks' gestation.

Abstract
Opioid use disorder (OUD) is a chronic, relapsing condition, often associated with legal, interpersonal, and employment problems. Medications demonstrated to be effective for OUD are methadone (a full opioid agonist), buprenorphine (a partial agonist), and naltrexone (an opioid antagonist). Methadone and buprenorphine act by suppressing opioid withdrawal symptoms and attenuating the effects of other opioids. Naltrexone blocks the effects of opioid agonists. Oral methadone has the strongest evidence for effectiveness. Longer duration of treatment allows restoration of social connections and is associated with better outcomes. Treatments for OUD may be limited by poor adherence to treatment recommendations and by high rates of relapse and increased risk of overdose after leaving treatment. Treatment with methadone and buprenorphine has the additional risk of diversion and misuse of medication. New depot and implant formulations of buprenorphine and naltrexone have been developed to address issues of safety and problems of poor treatment adherence. For people with OUD who do not respond to these treatments, there is accumulating evidence for supervised injectable opioid treatment (prescribing pharmaceutical heroin). Another medication mode of minimizing risk of overdose is take-home naloxone. Naloxone is an opioid antagonist used to reverse opioid overdose, and take-home naloxone programs aim to prevent fatal overdose. All medication-assisted treatment is limited by lack of access and by stigma. In seeking to stem the rising toll from OUD, expanding access to approved treatment such as methadone, for which there remains the best evidence of efficacy, may be the most useful approach.

Abstract
BACKGROUND With expanding recreational cannabis legalisation, pregnant women and their offspring are at risk of potentially harmful consequences. OBJECTIVES To assess the prevalence of recreational cannabis use among pregnant women, health outcomes associated with prenatal recreational cannabis use, and the potential impact of recreational cannabis legalisation on this population. SEARCH STRATEGY Five databases and the grey literature were systematically searched (2000-2019). SELECTION CRITERIA Human studies published in English or French reporting on the prevalence of prenatal recreational cannabis use in high-income countries. DATA COLLECTION AND ANALYSIS Data on study characteristics, prenatal substance use, and health outcomes were extracted and qualitatively synthesised. MAIN RESULTS Forty-one publications met our inclusion criteria. The overall prevalence of prenatal cannabis use varied substantially (min-max: 0.24-22.6%), with the greatest use in the first trimester. In the three studies with temporal data available, rates of prenatal cannabis use increased across years. Only 7/41 and 5/41 studies provided information on gestational age of exposure and frequency of use, respectively. The concomitant use of alcohol, illicit drugs, and tobacco was higher among cannabis users than nonusers. Prenatal cannabis use was associated with select neonatal, but not maternal, health outcomes. There were insufficient data to compare prenatal cannabis use between the pre- and post-legalisation periods. CONCLUSION Cannabis use among pregnant women is prevalent and may be associated with adverse neonatal outcomes. Future studies should assess the gestational age and frequency of cannabis exposure, and usage patterns prior to and following legalisation. TWEETABLE ABSTRACT Women who consume cannabis during pregnancy could risk predisposing their newborns to poor birth outcomes.

Abstract
AIM Substance use is not unusual among women of childbearing age. Pregnant women who use a substance and the consequent impacts on a newborn vary across studies and settings. We reviewed New Zealand and Australian literature to examine the short-term health outcomes of newborn of substance-using mothers and their demographic characteristics. METHODS Five medical/nursing databases and google scholar were searched in April 2017. Studies were considered eligible if they described outcomes of newborn of substance-using mothers. Mixed Methods Appraisal Tool was used for quality assessment of candidate studies. Relevant data were extracted and analyzed using narrative synthesis. Based on data availability, a subset of studies was included in meta-analysis. RESULTS Although findings of individual studies vary, there are some evidence that the infants born to substance-using mothers were likely to have preterm birth, low birthweight, small-for-gestational age, low Apgar score, and admission to neo-natal intensive care unit. The likelihood of adverse health outcomes was much higher for newborns of polysubstance-using mothers, than newborns of mothers using a single substance. Pregnant women who use illicit substance are predominantly socially disadvantaged, in their twenties and or of Aboriginal descent. CONCLUSION Infants of substance-using mothers suffer a range of adverse health outcomes. Multidisciplinary and integrated approach of services that ensure supportive social determinants of health may result in a better outcome for newborn and positive behavioral change among mothers.

Abstract
Objectives Substance use during pregnancy is a significant public health issue. Prenatal substance use increased in the past decade while prenatal cigarette smoking has remained stable. Co-use of tobacco and other drugs is a concern because of potential additive risks. This study aims to describe the prevalence rates of substance use among pregnant women and examine the association between smoking status (nonsmoker, recent quitter and current smoker) and other drug use. Methods In this cross-sectional study, pregnant women (n = 500) were recruited from two obstetric practices to complete three substance use screeners and have their urine tested for 12 different drug classes, including cannabis, opioids and cocaine. Participants were divided into three groups based on survey responses: nonsmokers, recent quitters (smoked in the month prior to pregnancy but not past month) and current smokers (past-month). Results Approximately 29% of participants reported smoking in the month before pregnancy. During pregnancy, 17, 12 and 71% were current smokers, recent quitters and nonsmokers respectively. Overall prevalence of illicit or prescription drug use in pregnancy was 27%. Cannabis was the most common drug used in pregnancy with prevalence of 22%, followed by opioids (4%), cocaine (1%), tricyclic antidepressants (TCAs) (1%), amphetamines (1%), and benzodiazepines (1%). On multivariable logistic regression, smoking in pregnancy was associated with a positive urine drug screen; with adjusted odds ratio (aOR) 4.7 (95% CI 2.6-8.3) for current smokers and 1.6 (95% CI 0.8-3.3) for recent quitters. Factors negatively associated with positive drug screen were second and third trimester pregnancies, 0.5 (0.3-0.9) and 0.3 (0.2-0.6) respectively; and employment, 0.5 (0.3-0.8). Conclusions for Practice Co-use of tobacco and illicit drugs, particularly cannabis, is relatively high during pregnancy. Additional research is needed to understand the health implications of co-use versus use of tobacco only. Given the strong association between smoking and other drug use, clinicians should routinely assess for illicit drug use in women who smoke during pregnancy.

Abstract
Introduction Intrauterine fetal demise affects between 0.4-0.8% of pregnancies worldwide. This significant adverse pregnancy outcome continues to be poorly understood. In utero exposure to substances increases the risk of stillbirth to varying degrees according to the type of substance and degree of exposure. The aim of this qualitative narrative review is to investigate common biologic relationships between stillbirth and maternal substance use. Methods A PubMed literature search was conducted to query the most commonly used substances and biologic mechanisms of stillbirth. Search terms included "stillbirth," "intrauterine fetal demise," "placenta," "cocaine," "tobacco," "alcohol," "methamphetamines," "opioids/ opiates," and "cannabis." Results There are very few studies identifying a direct link between substance use and stillbirth. Several studies demonstrate associations with placental lesions of insufficiency including poor invasion, vasoconstriction, and sequestration of toxic substances that inhibit nutrient transport. Restricted fetal growth is the most common finding in pregnancies complicated by all types of substance use. Discussion More research is needed to understand the biologic mechanisms of stillbirth. Such knowledge will be foundational to understanding how to prevent and treat the adverse effects of substances during pregnancy.

Abstract
Objective The effects of suicidal behavior on obstetric outcomes remain dangerously unquantified. We sought to report on the risk of adverse obstetric outcomes for US women with suicidal behavior at the time of delivery. Methods We performed a cross-sectional analysis of delivery hospitalizations from 2007–2012 National (Nationwide) Inpatient Sample. From the same hospitalization record, International Classification of Diseases codes were used to identify suicidal behavior and adverse obstetric outcomes. Adjusted odds ratios (aOR) and 95% confidence intervals (CI) were obtained using logistic regression. Results Of the 23,507,597 delivery hospitalizations, 2,180 were complicated by suicidal behavior. Women with suicidal behavior were at a heightened risk for outcomes including antepartum hemorrhage (aOR = 2.34; 95% CI: 1.47–3.74), placental abruption (aOR = 2.07; 95% CI: 1.17–3.66), postpartum hemorrhage (aOR = 2.33; 95% CI: 1.61–3.37), premature delivery (aOR = 3.08; 95% CI: 2.43–3.90), stillbirth (aOR = 10.73; 95% CI: 7.41–15.56), poor fetal growth (aOR = 1.70; 95% CI: 1.10–2.62), and fetal anomalies (aOR = 3.72; 95% CI: 2.57–5.40). No significant association was observed for maternal suicidal behavior with cesarean delivery, induction of labor, premature rupture of membranes, excessive fetal growth, and fetal distress. The mean length of stay was longer for women with suicidal behavior. Conclusion During delivery hospitalization, women with suicidal behavior are at increased risk for many adverse obstetric outcomes, highlighting the importance of screening for and providing appropriate clinical care for women with suicidal behavior during pregnancy.

Abstract
INTRODUCTION The aim of this paper was to provide an in-depth analysis of all stillbirth causation over a period of 10 years in a busy maternity unit located in a socioeconomically disadvantaged urban area, with an emphasis on overlapping pathology. MATERIALS AND METHODS A retrospective analysis of all structurally normal stillbirths in singleton pregnancies born during 2002-2012. The PSANZ stillbirth classification was used; per stillbirth subgroup main risk factors were evaluated. RESULTS Out of 130 cases, 43% showed overlapping pathologies. In the remaining 74 (56%) cases, the following single pathologies were found: IUGR 20 (15%), infection 12 (9%), abruption 8 (6%), placental thrombotic pathology 8 (6%), miscellaneous 6 stillbirths (5%), and 20 cases (15%) unexplained. Smoking was a risk factor for stillbirth associated with abruption (OR 3.639), infection (OR 2.271), and thrombotic pathology (OR 2.168). Drug use had an association with (placental) infection (OR 3.598). Obesity showed a significant association with IUGR (OR 3.782) and abruption (OR 9.040). Thrombophilia risk analysis for the overall group of stillbirths showed significant results for Protein S (OR 8.889) and homocysteine >90th centile (OR 2.087). CONCLUSIONS Overlapping pathology was identified in 43% of stillbirths. Infection, IUGR, and abruption were the most important single cause of stillbirth.

Abstract
BACKGROUND Several epidemiological studies have determined that maternal smoking can increase the risk of placenta abruption. To date, only a meta-analysis has been performed for assessing the relationship between smoking and placenta abruption. This meta-analysis was conducted to estimate the association between smoking and the risk of placenta abruption. METHODS A literature search was conducted in major databases such as PubMed, Web of Science, and Scopus from the earliest possible year to April 2016. The heterogeneity across studies was explored by Q-test and I2 statistic. The publication bias was assessed using Begg's and Egger's tests. The results were reported using odds ratio (OR) estimate with its 95% confidence intervals (CI) using a random effects model. RESULTS The literature search yielded 1167 publications until April 2016 with 4 309 610 participants. Based on OR estimates obtained from case-control and cohort studies, there was a significant association between smoking and placenta abruption (1.80; 95% CI: 1.75, 1.85). Based on the results of cohort studies, smoking and placenta abruption had a significant association (relative risk ratio: 1.65; 95% CI: 1.51, 1.80). CONCLUSIONS Based on reports in epidemiological studies, we showed that smoking is a risk factor for placenta abruption.

Abstract
Much has been written about the consequences of substance use in pregnancy, but there has been far less focus on the prevention of unintended pregnancies in women with substance use disorders (SUDs). We examine the literature on pregnancy incidence for women with SUDs, the clinical and economic benefits of increasing access to long-acting reversible contraceptive (LARC) methods in this population, and the current hurdles to increased access and uptake. High rates of unintended pregnancies and poor physical and psychosocial outcomes among women with SUDs underscore the need for increased access to, and uptake of, LARC methods among these women. A small number of studies that focused on improving access to contraception, especially LARC, via integrated contraception services predominantly provided in drug treatment programs were identified. However, a number of barriers remain, highlighting that much more research is needed in this area.

Abstract
Stillbirth is one of the most adverse pregnancy outcomes. The rate of stillbirth in high income countries has remained stagnant in recent decades. This study aimed to determine the incidence and risk factors of stillbirths specific to hospital-based deliveries in a secondary level hospital in Melbourne, Australia, over a 5-year period. We conducted a case-control study from January 2007 to December 2011. Univariate and multivariate analyses were conducted in STATA 12.1. The 5-year cumulative incidence of still-birth was 5.3 per 1000 total births (95% CI 4.3, 6.5). Univariate analysis revealed that higher body-mass index, smoking during pregnancy, haemoglobin level (≥14.5 g/dl), previous stillbirth, primiparity, marital status, previous caesarean section and reduced foetal movement in the 2 weeks prior to delivery were associated with increased risk of stillbirth. However, after adjustment for confounders in a multiple-regression model, only previous caesarean section (p = 0.006), unmarried (p = 0.004), high haemoglobin level (p = 0.007) and reduced foetal movement in the 2 weeks prior to delivery (p < 0.001) remained significantly associated with increased risk of stillbirth. The characteristics of our study population was similar to the population of state-wide survey in 2009, however, the incidence in our study was slightly lower. We concluded that previous caesarean section, pregnancy while being unmarried, higher haemoglobin level and reduced foetal movement in the 2 weeks before delivery were significant predictors of stillbirth. The identified risk factors were similar to other studies and the obstetric practice at the hospital or the demographics of the study population did not add to additional risk.

Abstract
Opioid use in pregnancy has increased dramatically over the past decade. Since prenatal opioid use is associated with numerous obstetrical and neonatal complications, this now has become a major public health problem. In particular, in utero opioid exposure can result in neonatal abstinence syndrome (NAS) which is a serious condition characterized by central nervous system hyperirritability and autonomic nervous system dysfunction. The present review seeks to define current practices regarding the approach to the pregnant mother and neonate with prenatal opiate exposure. Although the cornerstone of prenatal management of opioid dependence is opioid maintenance therapy, the ideal agent has yet to be definitively established. Pharmacologic management of NAS is also highly variable and may include an opioid, barbiturate, and/or α-agonist. Genetic factors appear to be associated with the incidence and severity of NAS. Establishing pharmacogenetic risk factors for the development of NAS has the potential for creating opportunities for "personalized genomic medicine" and novel, individualized therapeutic interventions.

Abstract
How the fetus withstands an environment of reduced oxygenation during life in the womb has been a vibrant area of research since this field was introduced by Joseph Barcroft, a century ago. Studies spanning five decades have since used the chronically instrumented fetal sheep preparation to investigate the fetal compensatory responses to hypoxia. This defence is contingent on the fetal cardiovascular system, which in late gestation adopts strategies to decrease oxygen consumption and redistribute the cardiac output away from peripheral vascular beds and towards essential circulations, such as those perfusing the brain. The introduction of simultaneous measurement of blood flow in the fetal carotid and femoral circulations by ultrasonic transducers has permitted investigation of the dynamics of the fetal brain sparing response for the first time. Now we know that major components of fetal brain sparing during acute hypoxia are triggered exclusively by a carotid chemoreflex and that they are modified by endocrine agents and the recently discovered vascular oxidant tone. The latter is determined by the interaction between nitric oxide and reactive oxygen species. The fetal brain sparing response matures as the fetus approaches term, in association with the prepartum increase in fetal plasma cortisol, and treatment of the preterm fetus with clinically relevant doses of synthetic steroids mimics this maturation. Despite intense interest into how the fetal brain sparing response may be affected by adverse intrauterine conditions, this area of research has been comparatively scant, but it is likely to take centre stage in the near future.

Abstract
This study compared the latency of pattern reversal visual evoked potentials (VEP) of 36-month old children exposed to opioid pharmacotherapy in utero to that of a group of non-exposed children. Pregnant women were enrolled as part of an open-label non-randomised flexible dosing longitudinal study. Participants were 21 children whose mothers were treated with buprenorphine- (n=11) or methadone-pharmacotherapy (n=10) during pregnancy, and 15 children not exposed to opioids in pregnancy. One-way between groups analyses of variance (ANOVA) were conducted to test the statistical significance of differences between the mean latencies of the peak response to two different sized checkerboard patterns (48' and 69' of retinal arc). Standard multiple regression analyses were conducted to determine whether there was a significant relationship between group status and VEP latencies after adjusting for the effect of covariates. VEP latencies ranged from 98 to 112 milliseconds (ms) for checks of 48' arc, and from 95 to 113ms for checks of 69' arc. Latencies were comparable across groups. After adjusting for covariates children prenatally exposed to methadone or buprenorphine did not differ significantly from non-opioid exposed children in their responses to either check size. Nor were there any significant differences in VEP latencies between children prenatally exposed to methadone and children prenatally exposed to buprenorphine. Head circumference (HC) was significantly associated with P100 latencies for both check sizes. Data from this controlled, non-randomised study suggest that neither buprenorphine nor methadone appear to have any long-term effects on visual maturity assessed at 36months of age.

Abstract
BACKGROUND Children of heroin-using women have a higher risk of unfavorable health and developmental outcomes. Although methadone maintenance treatment (MMT) has been widely used to treat heroin-using pregnant women, potential effects on accessibility and utilization of healthcare service for their offspring are less explored. METHODS We used four national registry and health insurance datasets in Taiwan from 2004 to 2009 to form a population-based matched retrospective cohort study. A total of 1056 neonates born to women in the MMT program (857 born before mother's enrollment in the MMT program [BM], 199 born after mother's enrollment in the MMT program [AM]) was established; 10547 matched non-drug [ND] exposed neonates were identified for comparison. Outcome variables included offspring's health insurance coverage and utilization of preventive, outpatient, and emergency room cares in the first year after birth. RESULTS Infants born to mothers on MMT were more likely to have no or incomplete insurance coverage (BM: adjusted odds ratio [aOR]=1.29, 95% CI: 1.10-1.53; AM: aOR=1.56, 95% CI: 1.14-2.13) as compared with the socioeconomic status-matched ND group. The BM infants appeared to have fewer preventive care visits (adjusted relative risk [aRR]=0.85, 95% CI: 0.80-0.90), whereas the AM infants utilized outpatient and emergency room services more frequently (outpatient: aRR=1.11, 95% CI: 1.01-1.23; emergency: aRR=1.46, 95% CI: 1.11-1.90). CONCLUSIONS Addiction treatment and harm reduction programs for women of childbearing ages should be delivered in the coordinated framework that ensures comprehensiveness and continuity in healthcare and social services.

Abstract
BACKGROUND Substance use decreases in pregnancy but little prospective data are available on the rates of abstinence and relapse for specific substances. This study compared rates of abstinence in pregnancy and relapse postpartum for nicotine cigarettes, alcohol, marijuana, and cocaine. METHODS Data from 152 women drawn from a randomized controlled trial comparing psychological treatments for substance use in pregnancy were analyzed. Self-reports of substance use and urine for toxicology testing throughout pregnancy and 3-months, 12-months and 24-months post-delivery were collected. Multivariate Cox models were used to compare rates of abstinence and relapse across substances. RESULTS In pregnancy, 83% of all women achieved abstinence to at least one substance. The mean (SE) days to abstinence was 145.81 (9.17), 132.01 (6.17), 151.52 (6.24), and 148.91 (7.68) for cigarettes, alcohol, marijuana and cocaine, respectively. Participants were more likely to achieve abstinence from alcohol (HR 7.24; 95% CI 4.47-11.72), marijuana (HR 4.06; 95% CI 1.87-6.22), and cocaine (HR 3.41; 95% CI 2.53-6.51), than cigarettes. Postpartum, 80% of women abstinent in the last month of pregnancy relapsed to at least one substance. The mean days to relapse was 109.67 (26.34), 127.73 (21.29), 138.35 (25.46), and 287.55 (95.85) for cigarettes, alcohol, marijuana and cocaine, respectively. Relapse to cocaine was only 34% (HR 0.34; 95% CI 0.15-0.77) that of cigarettes. CONCLUSIONS Pregnancy-related abstinence rates were high for all substances except cigarettes. Postpartum relapse was common, with cocaine using women being less likely to relapse after attaining abstinence compared to women using cigarettes, alcohol or marijuana.

Abstract
OBJECTIVE The purpose of this report was to examine the course of smoking among pregnant women with concurrent substance use, and to assess the impact of depression on smoking. METHODS Data were gathered as part of a randomized controlled trial assessing the efficacy of substance abuse treatment in pregnant women. Women (n=176) were recruited before 28 completed weeks of pregnancy, and followed until 3months postpartum. Depression was assessed using the Inventory of Depressive Symptomatology and the MINI Neuropsychiatric Interview. Our outcome was the average number of cigarettes smoked per day. Linear mixed effects regression was used to measure differential changes in smoking. RESULTS 66% of women smoked in the three months before pregnancy, 42% of pre-pregnancy smokers achieved abstinence before delivery and 60% of the baseline cohort smoked postpartum. Smoking did not differ significantly between depressed and non-depressed groups. After delivery both groups increased smoking at similar rates. CONCLUSION Smoking was common among our cohort of pregnant women with a history of substance use. Women were able to discontinue or decrease smoking during pregnancy, but were likely to resume or increase smoking postpartum. Having clinically significant depressive symptoms or a diagnosis of depression did not have an obvious effect on smoking behaviors.

Abstract
OBJECTIVE To compare illicit drug and smoking use in pregnancies with and without stillbirth. METHODS The Stillbirth Collaborative Research Network conducted a case-control study from March 2006 to September 2008, covering more than 90% of deliveries to residents of five a priori-defined geographically diverse regions. The study attempted to include all stillbirths and representative liveborn controls. Umbilical cord samples from cases and controls were collected and frozen for subsequent batch analysis. Maternal serum was collected at delivery and batch analyzed for cotinine. RESULTS For 663 stillbirth deliveries, 418 (63%) had cord homogenate and 579 (87%) had maternal cotinine assays performed. For 1,932 live birth deliveries, 1,050 (54%) had cord homogenate toxicology and 1,545 (80%) had maternal cotinine assays performed. A positive cord homogenate test for any illicit drug was associated with stillbirth (odds ratio [OR] 1.94, 95% confidence interval [CI] 1.16-3.27). The most common individual drug was cannabis (OR 2.34 95% CI 1.13-4.81), although the effect was partially confounded by smoking. Both maternal self-reported smoking history and maternal serum cotinine levels were associated in a dose-response relationship with stillbirth. Positive serum cotinine less than 3 ng/mL and no reported history of smoking (proxy for passive smoke exposure) also were associated with stillbirth (OR 2.06, 95% CI 1.24-3.41). CONCLUSION Cannabis use, smoking, illicit drug use, and apparent exposure to second-hand smoke, separately or in combination, during pregnancy were associated with an increased risk of stillbirth. Because cannabis use may be increasing with increased legalization, the relevance of these findings may increase as well. LEVEL OF EVIDENCE II.

OBJECTIVE To compare obstetric outcomes in women using illegal drugs with women who smoke cigarettes. DESIGN Retrospective cohort study. SETTING Aberdeen, UK. POPULATION All deliveries in Aberdeen in women using illegal drugs and women who smoked cigarettes during 1997-2007. MATERIAL AND METHODS The women who used illegal drugs were identified from a database of affected pregnant women in Aberdeen. The Aberdeen Maternity and Neonatal Databank was used to identify women who smoke cigarettes and to obtain pregnancy outcome information. Sociodemographic characteristics, maternal and perinatal outcomes were compared using chi-squared test, independent sample t-test and logistic regression analysis. MAIN OUTCOME MEASURES Preterm delivery, low birthweight (standardized birthweight score <-2) and admission to the neonatal unit. RESULTS Of the 561 illegal drug users, 96% were also cigarette smokers. Compared with women who smoke cigarettes with no reported illegal drug use, they were significantly more likely to have a preterm delivery [adjusted odds ratio (aOR) 1.6 (95% confidence interval (CI) 1.3-2.1)], low birthweight baby [aOR 1.9 (95%CI 1.4-2.6)], baby admitted to the neonatal unit [aOR 13.3 (95%CI 10.9-16.3)], deep vein thrombosis [aOR (95%CI 8.8-50.8)] and antepartum hemorrhage [aOR (95%CI 1.2-2.1)]. They were less likely to be at the extremes of age, or to develop pregnancy-induced hypertension [aOR 0.3 (95%CI 0.2-0.4)]. CONCLUSION Illegal drug use in pregnancy appears to increase the risk of adverse outcomes, over and above that related to cigarette smoking, but appears to be associated with lower prevalence of gestational hypertension.

Abstract
AIMS To ascertain the characteristics and short-term outcomes of infants born to illicit drug-using mothers in public hospitals in the state of New South Wales and the Australian Capital Territory during 2004. METHODS Patients were identified retrospectively by hospital records searches using ICD-10 morbidity codes and records of local Drug and Alcohol Services. Records were reviewed on site. All public hospitals (n= 101) with obstetric services were included. RESULTS A total of 879 (1.4%, 95% confidence interval: 1.3-1.5%) drug-using mothers were identified from 62,682 confinements. Opiates (46.8%), amphetamines (23.0%) and polydrug (16.4%) exposure were most common. There were eight stillbirths. Among these 871 infants, prematurity (23.6%) and low birthweight (27.1%) were common and 51.1% were admitted to nurseries for further care. Two infants died. Major congenital anomalies were detected in 15 infants. Pharmacological treatment for withdrawal was required for 202 (23.2%), and 143 (70.8%) infants were discharged home on medication. Infants who completed inpatient pharmacological treatment were hospitalised longer (median 26.0 vs. 12.0 days) and were more likely to be premature (37.3 vs. 14.0%). Child-at-risk notifications affected 40.6% of the infants, and 7.6% were fostered prior to discharge. A total of 333 (38.2%) infants were breastfed at discharge. CONCLUSIONS Our regional study highlights a substantial prevalence of drug use in pregnancy with considerable adverse perinatal and hospital outcomes in infants born to these mothers. Coordinated health care and resources are needed to support these mother-infant pairs because of their social, medical and mental-health issues.

Abstract
Background. There is a paucity of research in Australia on the characteristics of women in treatment for illicit substance use in pregnancy and the health outcomes of their neonates. Aims. To determine the clinical features and outcomes of high-risk, marginalized women seeking treatment for illicit substance use in pregnancy and their neonates. Methods. 139 women with a history of substance abuse/dependence engaged with a perinatal drug health service in Sydney, Australia. Maternal (demographic, drug use, psychological, physical, obstetric, and antenatal care) and neonatal characteristics (delivery, early health outcomes) were examined. Results. Compared to national figures, pregnant women attending a specialist perinatal and family drug health service were more likely to report being Australian born, Aboriginal or Torres Strait Islander, younger, unemployed, and multiparous. Opiates were the primary drug of concern (81.3%). Pregnancy complications were common (61.9%). Neonates were more likely to be preterm, have low birth weight, and be admitted to special care nursery. NAS was the most prevalent birth complication (69.8%) and almost half required pharmacotherapy. Conclusion. Mother-infant dyads affected by substance use in pregnancy are at significant risk. There is a need to review clinical models of care and examine the longer-term impacts on infant development.

Abstract
Opioid use in pregnant women has increased over the last decade. Following birth, infants with in utero exposure demonstrate signs and symptoms of withdrawal known as the neonatal abstinence syndrome (NAS). Infants express a spectrum of disease, with most requiring the administration of pharmacologic therapy to ensure proper growth and development. Treatment often involves prolonged hospitalization. There is a general lack of high-quality clinical trial data to guide optimal therapy, and significant heterogeneity in treatment approaches. Emerging trends in the treatment of infants with NAS include the use of sublingual buprenorphine, transition to outpatient therapy, and pharmacogenetic risk stratification.

Abstract
AIMS To compare clinical status, mother-to-child transmission (MTCT) rates, use of prevention of (PMTCT) interventions and pregnancy outcomes between HIV-infected injecting drug users (IDUs) and non-IDUs. DESIGN AND SETTING Prospective cohort study conducted in seven human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) Centres in Ukraine, 2000-10. PARTICIPANTS Pregnant HIV-infected women, identified before/during pregnancy or intrapartum, and their live-born infants (n = 6200); 1028 women followed post-partum. MEASUREMENTS Maternal and delivery characteristics, PMTCT prophylaxis, MTCT rates, preterm delivery (PTD) and low birth weight (LBW). FINDINGS Of 6200 women, 1111 (18%) reported current/previous IDU. The proportion of IDUs diagnosed with HIV before conception increased from 31% in 2000/01 to 60% in 2008/09 (P < 0.01). Among women with undiagnosed HIV at conception, 20% of IDUs were diagnosed intrapartum versus 4% of non-IDUs (P < 0.01). At enrolment, 14% of IDUs had severe/advanced HIV symptoms versus 6% of non-IDUs (P < 0.001). IDUs had higher rates of PTD and LBW infants than non-IDUs, respectively, 16% versus 7% and 22% versus 10% (P < 0.001). IDUs were more likely to receive no neonatal or intrapartum PMTCT prophylaxis compared with non-IDUs (OR 2.81, p < 0.001). MTCT rates were 10.8% in IDUs versus 5.9% in non-IDUs; IDUs had increased MTCT risk (adjusted odds ratio 1.32, P = 0.049). Fewer IDUs with treatment indications received HAART compared with non-IDUs (58% versus 68%, P = 0.03). CONCLUSIONS Pregnant human immunodeficiency virus-infected injecting drug users in Ukraine have worse clinical status, poorer access to prevention of mother-to-child transmission prophylaxis and highly active antiretroviral therapy, more adverse pregnancy outcomes and higher risk of mother-to-child transmission than non-injecting drug user women.

Abstract
BACKGROUND Stillbirth rates in high-income countries have shown little or no improvement over the past two decades. Prevention strategies that target risk factors could be important in rate reduction. This systematic review and meta-analysis was done to identify priority areas for stillbirth prevention relevant to those countries. METHODS Population-based studies addressing risk factors for stillbirth were identified through database searches. The factors most frequently reported were identified and selected according to whether they could potentially be reduced through lifestyle or medical intervention. The numbers attributable to modifiable risk factors were calculated from data relating to the five high-income countries with the highest numbers of stillbirths and where all the data required for analysis were available. Odds ratios were calculated for selected risk factors, from which population-attributable risk (PAR) values were calculated. FINDINGS Of 6963 studies initially identified, 96 population-based studies were included. Maternal overweight and obesity (body-mass index >25 kg/m(2)) was the highest ranking modifiable risk factor, with PARs of 8-18% across the five countries and contributing to around 8000 stillbirths (≥22 weeks' gestation) annually across all high-income countries. Advanced maternal age (>35 years) and maternal smoking yielded PARs of 7-11% and 4-7%, respectively, and each year contribute to more than 4200 and 2800 stillbirths, respectively, across all high-income countries. In disadvantaged populations maternal smoking could contribute to 20% of stillbirths. Primiparity contributes to around 15% of stillbirths. Of the pregnancy disorders, small size for gestational age and abruption are the highest PARs (23% and 15%, respectively), which highlights the notable role of placental pathology in stillbirth. Pre-existing diabetes and hypertension remain important contributors to stillbirth in such countries. INTERPRETATION The raising of awareness and implementation of effective interventions for modifiable risk factors, such as overweight, obesity, maternal age, and smoking, are priorities for stillbirth prevention in high-income countries.

Abstract
BACKGROUND To date, no studies have used population-level data to investigate whether maternal location of residence (metropolitan vs. regional/remote populations) is associated with alcohol use in pregnancy. This information has important implications for appropriate service provision. METHODS Information on all live births in New South Wales, Australia, was linked to records of alcohol-related admissions for mothers of these births over a 6-year period (2000 to 2006). Cases were women who had at least 1 alcohol-related hospital admission during pregnancy or at birth. Controls were women who had at least 1 live birth over that same time period but no alcohol-related hospital admissions during that time. Admissions were considered to be alcohol-related based on the International Statistical Classification of Diseases and Related Health Problems, 10th Revision, Australian Modification (ICD-10-AM) code. Demographic, obstetric, and neonatal variables were compared. RESULTS A total of 417,464 singleton birth records were analyzed, 488 of which were coded positive for at least 1 alcohol-related ICD-10-AM diagnosis. Characteristics associated with alcohol-related admissions in pregnancy were residence in a remote/very remote area, being Australian-born, having had a previous pregnancy, smoking in the current pregnancy, and presenting late to antenatal care. Alcohol-exposed pregnancies were associated with a range of poor obstetric and neonatal outcomes, with no geographic differences noted. However, women in regional/remote areas were less likely to attend specialist obstetric hospitals. CONCLUSIONS This study shows the need for standardized screening programs for alcohol use in pregnancy and where problematic use is detected, for clear clinical guidelines on management and referral.

Abstract
We present the case of a 20-year-old student with an undiagnosed pregnancy who had taken ecstasy and LSD (lysergic acid diethylamide). Twenty-four hours later she delivered a stillborn term infant, and subsequently developed eclampsia with seizures, hypertension and proteinuria. Illicit drug use is relatively common in women of child-bearing age in Australia, and is a risk factor for adverse obstetric outcomes. Ecstasy (MDMA [3,4-methylenedioxymethamphetamine]) is a sympathomimetic amine, similar to amphetamine in its cardiovascular effects. LSD is a hallucinogen with complex pharmacology and has potential for significant compromise of placental blood flow. We propose that the combined vasoconstrictive effects of MDMA and LSD caused placental ischaemia, contributing to the fetal death and precipitating a cascade of endothelial dysfunction which resulted in an eclamptic syndrome.

Abstract
Genome stability is essential for normal foetal growth and development. To date, genome stability in human lymphocytes has not been studied in relation to late pregnancy diseases, such as pre-eclampsia (PE) and intrauterine growth restriction (IUGR), which can be life-threatening to mother and baby and together affect >10% of pregnancies. We performed a prospective cohort study investigating the association of maternal chromosomal damage in mid-pregnancy (20 weeks gestation) with pregnancy outcomes. Chromosome damage was measured using the cytokinesis-block micronucleus cytome (CBMNcyt) assay in peripheral blood lymphocytes. The odds ratio for PE and/or IUGR in a mixed cohort of low- and high-risk pregnancies (N = 136) and a cohort of only high-risk pregnancies (N = 91) was 15.97 (P = 0.001) and 17.85 (P = 0.007), respectively, if the frequency of lymphocytes with micronuclei (MN) at 20 weeks gestation was greater than the mean + 2 SDs of the cohort. These results suggest that the presence of lymphocyte MN is significantly increased in women who develop PE and/or IUGR before the clinical signs or symptoms appear relative to women with normal pregnancy outcomes. The CBMNcyt assay may provide a new approach for the early detection of women at risk of developing these late pregnancy diseases and for biomonitoring the efficacy of interventions to reduce DNA damage, which may in turn ameliorate pregnancy outcome.

Abstract
OBJECTIVE To determine if there are sex differences in risk and incidence of stillbirth, preterm delivery and small-for-gestational age (SGA) in pregnancies complicated by maternal asthma relative to a non-asthmatic population. STUDY DESIGN Univariant and multiple regression analysis of the incidence of preterm delivery, SGA and stillbirth in singleton pregnancies complicated by asthma in Newcastle, NSW, Australia, from 1995 to 1999. RESULTS Asthma complicated 12% of all singleton pregnancies. The incidence of preterm delivery was not significantly different between asthmatic (13%) and non-asthmatic (11%) pregnancies. Male fetuses (53%) were more likely to deliver preterm than female fetuses (47%) in both asthmatic and non-asthmatic populations. There were significantly more male neonates of pregnancies complicated by asthma that were SGA at term relative to those of the non-asthmatic population. There were significantly more preterm female neonates that were SGA in pregnancies complicated by asthma relative to those of the non-asthmatic population. Male fetuses were more likely to be associated with a stillbirth in pregnancies complicated by asthma than female fetuses. CONCLUSION The presence of maternal asthma during pregnancy increases the risk of stillbirth for the male fetus and is associated with changes in fetal growth, but does not increase the incidence of a preterm delivery.

Abstract
OBJECTIVE To examine the impact of maternal hepatitis B virus (HBV) or hepatitis C virus (HCV) carrier status on pregnancy outcomes. METHODS A population-based study was performed by comparing all pregnancies of HBsAg and/or anti-HCV seropositive women who delivered during the years 1988-2007 with all other pregnant women who delivered in the same period. Multivariable logistic regression models were constructed to control for confounders. RESULTS Seven hundred and forty-nine hepatitis seropositive pregnant women were identified out of 186 619 deliveries (0.4%). Maternal characteristics, as well as perinatal outcomes, were comparable between the HBV and HCV carriers. HBV/HCV carriers had higher rates of preterm deliveries (<37 weeks gestation; 11.5 vs. 7.9%, P<0.001), premature rupture of membranes (8.9 vs. 6.9%, P=0.026), placental abruption (1.5 vs. 0.7%, P=0.018), labour induction (33.9 vs. 28.1%, P<0.001) and Caesarean deliveries (19.0 vs. 13.2%, P<0.001). Higher rates of perinatal mortality (2.3 vs. 1.3%, P=0.016), congenital malformations (7.2 vs. 5.1%, P=0.01) and low birth weight (<2500 kg; 10.4 vs. 7.8%, P=0.009) were noted in newborns of hepatitis carriers compared with the control group. Controlling for possible confounders such as maternal age and parity by using multivariable analyses, the significant association between HBV or HCV carrier status and perinatal mortality, congenital malformations and low birth weight remained significant. CONCLUSIONS Maternal HBV or HCV carrier status is an independent risk factor for adverse perinatal outcome and careful surveillance is warranted.

Abstract
This study investigates the association between cigarette use and current mood/anxiety disorders among pregnant opioid-dependent patients. Pregnant methadone-maintained women (N = 122) completed the Addiction Severity Index and Structured Clinical Interview for DSM-IV. Participants were categorized based on past 30 days cigarette use: no (n = 15) and any smoking (n = 107); this latter group was then subdivided into light (one to ten cigarettes/day; n = 55), and heavy smokers (11+ cigarettes/day; n = 52). Any smoking was significantly associated with any current mood/anxiety disorder (p < 0.001), any current mood disorder (p = 0.007), and any current anxiety disorder (p < 0.001). No significant association was found between specific level of cigarette use and mood/anxiety disorders. This association between smoking and psychiatric disorders has implications for the mental and physical health of methadone-maintained women and their children, and may contribute to the understanding of the physiological mechanisms underlying smoking and nicotine dependence.
