Prenatal ethanol exposure programs an increased susceptibility of non-alcoholic fatty liver disease in female adult offspring rats. Toxicol Appl Pharmacol 2013; 274:263-73. [PMID: 24275070 DOI: 10.1016/j.taap.2013.11.009] [Citation(s) in RCA: 80] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2013] [Revised: 11/13/2013] [Accepted: 11/14/2013] [Indexed: 12/14/2022]
Abstract
Prenatal ethanol exposure (PEE) induces dyslipidemia and hyperglycemia in fetus and adult offspring. However, whether PEE increases the susceptibility to non-alcoholic fatty liver disease (NAFLD) in offspring and its underlying mechanism remain unknown. This study aimed to demonstrate an increased susceptibility to high-fat diet (HFD)-induced NAFLD and its intrauterine programming mechanisms in female rat offspring with PEE. Rat model of intrauterine growth retardation (IUGR) was established by PEE, the female fetus and adult offspring that fed normal diet (ND) or HFD were sacrificed. The results showed that, in PEE+ND group, serum corticosterone (CORT) slightly decreased and insulin-like growth factor-1 (IGF-1) and glucose increased with partial catch-up growth; In PEE+HFD group, serum CORT decreased, while serum IGF-1, glucose and triglyceride (TG) increased, with notable catch-up growth, higher metabolic status and NAFLD formation. Enhanced liver expression of the IGF-1 pathway, gluconeogenesis, and lipid synthesis as well as reduced expression of lipid output were accompanied in PEE+HFD group. In PEE fetus, serum CORT increased while IGF-1 decreased, with low body weight, hyperglycemia, and hepatocyte ultrastructural changes. Hepatic IGF-1 expression as well as lipid output was down-regulated, while lipid synthesis significantly increased. Based on these findings, we propose a "two-programming" hypothesis for an increased susceptibility to HFD-induced NAFLD in female offspring of PEE. That is, the intrauterine programming of liver glucose and lipid metabolic function is "the first programming", and postnatal adaptive catch-up growth triggered by intrauterine programming of GC-IGF1 axis acts as "the second programming".

Abstract
AIMS The study aimed to investigate (a) the association between low to moderate prenatal alcohol exposure (PAE) and the use of alcohol, tobacco and illicit drugs in adolescence and (b) whether the associations are modified by gender and ethnicity. METHODS The subjects of the study were 5922 children and adolescents, aged from 11 to 17 years, enrolled in the cross-sectional German Health Interview and Examination Survey for Children and Adolescents (the KiGGS study). Information on PAE is based on parental self-report questionnaires. Use of alcohol, tobacco and illicit drugs was assessed through self-report questionnaires for adolescents. RESULTS Low to moderate PAE was associated with an increased risk of drinking alcohol (adjusted odds ratio (OR) 1.73, 95% confidence interval (CI) 1.34, 2.18) and also of illicit drug use (adjusted OR 1.62, 95% CI 1.23, 2.14). The associations between PAE and the use of alcohol, tobacco and illicit drugs differed according to gender and ethnicity. Gender-stratified analyses resulted in adverse effects of PAE on drinking alcohol, smoking and illicit drug use in females; however, in German males, the associations disappeared. Stronger associations between PAE and the outcome measures were found in non-Germans. CONCLUSIONS Our findings indicate that low to moderate levels of maternal alcohol intake during pregnancy are a risk factor for use of alcohol, tobacco and illicit drugs by the offspring, with stronger associations in females and non-Germans.

Abstract
OBJECTIVES To investigate whether maternal negative affectivity, a tendency to frequent negative emotions and views, is associated with light alcohol use and binge drinking during pregnancy. DESIGN Cohort. SETTING Norway 1999-2008. POPULATION The study includes complete information on 66 111 pregnant women and their partners. METHODS We used data from the Norwegian Mother and Child Cohort study (MoBa) representing 39% of the pregnant population. MAIN OUTCOME MEASURES Light alcohol use (0.5-2 units one to four times per month) and binge drinking (an intake of 5 alcohol units or more) measured with the Alcohol Use Disorder Identification Test-Consumption (AUDIT-C). RESULTS For each unit increase in maternal negative affectivity the odds for light alcohol use increased with 27% in the first trimester [95% confidence interval (CI) 1.19-1.36], and 28% in the second trimester (95% CI 1.18-1.39). With respect to binge drinking, each unit increase in maternal negative affectivity was associated with 55% higher odds in the first trimester (95% CI 1.44-1.67), and 114% higher odds in the second trimester (95% CI 1.70-2.69). CONCLUSIONS Negative affectivity is associated with both light alcohol use and binge drinking during pregnancy. The mechanisms mediating the relation between negative affectivity and alcohol use in pregnancy should be investigated further.

Abstract
BACKGROUND The impact of low-to-moderate levels of alcohol consumption during pregnancy on child cognitive outcomes has been of recent concern. This study has tested the hypothesis that low-to-moderate maternal alcohol use in pregnancy is associated with lower school test scores at age 11 in the offspring via intrauterine mechanisms. METHODS We used data from the Avon Longitudinal Study of Parents and Children (ALSPAC), a birth cohort study based in the South West of England. Analyses were conducted on 7062 participants who had complete data on: maternal and paternal patterns of alcohol use in the first trimester and at 18 weeks' gestation, child's academic outcomes measured at age 11, gender, maternal age, parity, marital status, ethnicity, household crowding, home ownership status and parental education. We contrasted the association of mother's alcohol consumption during pregnancy with child's National Curriculum Key Stage 2 (KS2) test scores with the association for father's alcohol consumption (during the time the mother was pregnant) with child's National Curriculum Key Stage 2 (KS2) test scores. We used multivariate linear regression to estimate mean differences and 95% confidence intervals [CI] in KS2 scores across the exposure categories and computed f statistics to compare maternal and paternal associations. FINDINGS AND CONCLUSIONS Drinking up to 1 unit of alcohol a day during pregnancy was not associated with lower test scores. However, frequent prenatal consumption of 4 units (equivalent to 32 grams of alcohol) on each single drinking occasion was associated with reduced educational attainment [Mean change in offspring KS2 score was -0.68 (-1.03, -0.33) for maternal alcohol categories compared to 0.27 (0.07, 0.46) for paternal alcohol categories]. Frequent consumption of 4 units of alcohol during pregnancy may adversely affect childhood academic outcomes via intrauterine mechanisms.

Abstract
BACKGROUND There is no established safe level of alcohol consumption in pregnancy. Studies from Ireland have consistently shown lower abstention and higher binge drinking rates in pregnancy than other countries, indicating a high potential for foetal alcohol-related disorders. There has been little research on alcohol in pregnancy in primary care. AIMS To determine the prevalence of alcohol consumption amongst pregnant women attending their GP for antenatal care, and to compare this to use in the year prior to conception. METHODS Prospective cross-sectional study was carried out in fifteen teaching practices in the greater Dublin area. Women were recruited at their antenatal visits. Data were gathered by self-completed questionnaire in the practice, or researcher-administered telephone questionnaire. The questionnaire was based on the AUDIT, a WHO-validated data collection instrument designed for use in primary care. RESULTS Two hundred and forty valid questionnaires were returned (80 % recruitment rate). Alcohol intake and binge drinking levels were much lower during pregnancy compared to the year prior to pregnancy (p < 0.001). There was a marked reduction in the prevalence of alcohol use in pregnancy compared to previous research. Over 97 % drink no more than once a week, including almost two-thirds of women who abstain totally from alcohol in pregnancy. Non-pregnant Irish women drink alcohol more frequently, and with higher rates of binge drinking, than women of other nationalities. CONCLUSIONS Primary care is a suitable setting to research alcohol use in pregnancy. Alcohol use in pregnancy in Ireland has decreased markedly compared to previous research from this jurisdiction.

Abstract
ISSUES Alcohol exposure in utero is associated with a range of adverse outcomes in pregnancy and can cause long-term disability. Fetal alcohol spectrum disorder (FASD) is an umbrella term to describe a range of effects from prenatal alcohol exposure including fetal alcohol syndrome (FAS). Determining the prevalence of FASD is challenging. APPROACH This narrative review collates information on the prevalence of FASD in Australia and documents the various methods used for attaining estimates and the limitations of the available data. KEY FINDINGS Birth prevalence of FASD is most commonly measured through clinic-based studies, passive surveillance systems and active case ascertainment. Alcohol use in pregnancy and FAS in Australia is predominantly monitored through passive surveillance systems and under-ascertainment of cases is likely. State- and territory-based studies have reported birth prevalence rates of FAS of between 0.01 and 0.68 per 1000 live births. Prevalence rates of FASD have not been estimated in Australia. As reflected in the international data, Australian studies have found higher rates of FAS among some Indigenous communities. This likely reflects patterns of alcohol use and other socioeconomic risk factors. IMPLICATIONS Under-recognition of FASD reflects incomplete and inconsistent data collections recording alcohol use in pregnancy, lack of awareness among health professionals and a lack of diagnostic and support services. CONCLUSION Accurate measurement of FASD prevalence is crucial to inform policy, resource and service development in the areas of health, education, justice and community. There is a need for consensus on the collection and best use of data. [Burns L, Breen C, Bower C, O' Leary C, Elliott EJ.

Abstract
Prenatal alcohol exposure is known to have many profound detrimental effects on human fetal development (fetal alcohol spectrum disorders), which may manifest as lifelong disabilities. However, how alcohol affects the auditory/vestibular system is still largely unknown. This is the first study to investigate morphological effects of alcohol on the developing octavolateral system (the inner ear and lateral line) using the zebrafish, Danio rerio. Zebrafish embryos of 2 hours post fertilization (hpf) were treated in 2% alcohol for 48 hours and screened at 72 hpf for morphological defects of the inner ear and lateral line. Octavolateral organs from both alcohol-treated and control zebrafish were examined using light, confocal, and scanning electron microscopy. We observed several otolith phenotypes for alcohol-treated zebrafish including zero, one, two abnormal, two normal, and multiple otoliths. Results of this study show that alcohol treatment during early development impairs the inner ear (smaller ear, abnormal otoliths, and fewer sensory hair cells) and the lateral line (smaller neuromasts, fewer neuromasts and hair cells per neuromast, and shorter kinocilia of hair cells). Early embryonic alcohol exposure may also result in defects in hearing, balance, and hydrodynamic function of zebrafish.

Abstract
OBJECTIVE two studies aimed to explore the advice Dutch midwives give and the information Dutch pregnant women and partners of pregnant women receive about alcohol consumption in pregnancy. DESIGN study 1 included individual semi-structured interviews with midwives. Study 2 involved focus groups and individual semi-structured interviews with pregnant women and partners. Interview content was based on the I-Change Model. SETTING study 1 was conducted nation-wide; Study 2 was conducted in the central and southern regions of the Netherlands. PARTICIPANTS 10 midwives in Study 1; 25 pregnant women and nine partners in Study 2. MEASUREMENTS AND FINDINGS study 1 showed that midwives intended to advise complete abstinence, although this advice was mostly given when women indicated to consume alcohol. Midwives reported to lack good screening skills and sufficient knowledge about the mechanisms and consequences of antenatal alcohol use and did not involve partners in their alcohol advice. In Study 2, the views of pregnant women and partners were congruent to the findings reported in Study 1. In addition, pregnant women and partners considered midwives as an important source of information on alcohol in pregnancy. Partners were interested in the subject, had a liberal view on antenatal alcohol use and felt ignored by midwives and websites. Pregnant women indicated to receive conflicting alcohol advice from their health professionals. KEY CONCLUSIONS midwives' alcohol advice requires improvement with regard to screening, knowledge about mechanisms and consequences of antenatal alcohol use and the involvement of the partners in alcohol advice during pregnancy. IMPLICATIONS FOR PRACTICE training should be given to Dutch midwives to increase their screening skills and their alcohol related knowledge to pregnant women. Research is needed to determine how the midwife's alcohol advice to the partner should be framed in order to optimise the partner's involvement concerning alcohol abstinence in pregnancy. More attention to the topic at a national level, for example via mass media campaigns, should also be considered to change views about alcohol use during pregnancy in all stakeholders.

Abstract
PURPOSE OF REVIEW This article addresses the question of 'best treatment options', which clinicians face when treating pregnant women with alcohol and opioid dependence. RECENT FINDINGS Studies show that alcohol consumption is associated with fetal abnormalities and long-term cognitive problems depending on the amount consumed, drinking pattern, and time of gestation. Screening and evaluation of specific interventions are important to reduce alcohol consumption during pregnancy and associated problems in infants. Opioid detoxification is only recommended beyond the first trimester and only in those pregnant women who refuse opioid maintenance therapy. Methadone is the most established treatment of pregnant opioid-dependent women, though recent results indicate some advantages of buprenorphine, slow-release oral methadone and diamorphine compared with methadone. SUMMARY Benzodiazepines seem to be the most recommendable option for managing alcohol withdrawal, and psychosocial interventions succeed in reducing alcohol consumption or in maintaining abstinence in alcohol-dependent pregnant women. Regarding opioid dependence, current results suggest that factors like the health status of the mother, the need for additional medications (e.g. treatment for HIV), comorbid drug dependence, and concurrent drug use need to be considered in order to find the 'best opioid substitute'.

Abstract
Prenatal exposure to high-level ethanol (EtOH) has been reported to produce hyperlocomotion in offspring. Previous studies have demonstrated synaptic plasticity in cortical afferent to the dorsolateral (DL) striatum is involved in the pathogensis of hyperlocomotion. Here, prenatal EtOH-exposed rat offspring were used to investigate whether maternal EtOH exposure affected synaptic plasticity in the DL striatum. We found high-frequency stimulation (HFS) induced a weaker long-term potentiation (LTP) in EtOH rats than that in control rats at postnatal day (PD) 15. The same protocol of HFS induced long-term depression (LTD) in control group but still LTP in EtOH group at PD 30 or PD 40. Furthermore, enhancement of basal synaptic transmission accompanied by the decrease of pair-pulse facilitation (PPF) was observed in PD 30 EtOH offspring. The perfusion with D1-type receptors (D1R) antagonist SCH23390 recovered synaptic transmission and blocked the induction of abnormal LTP in PD 30 EtOH offspring. The perfusion with D2-type receptors (D2R) agonist quinpirole reversed EtOH-induced LTP into D1R- and metabotropic glutamate receptor-dependent LTD. The data provide the functional evidence that prenatal ethanol exposure led to the persistent abnormal synaptic plasticity in the DL striatum via disturbing the balance between D1R and D2R.

Abstract
OBJECTIVES This study assesses factors that contribute to alcohol consumption during pregnancy and identifies potential intervention strategies to reduce consumption. METHODS The study sample includes 142 pregnant women who attended a public hospital for prenatal health care in Perth, Western Australia. All participants returned a self-completion survey. RESULTS Women who discontinued drinking during pregnancy were significantly more likely to be engaged in full time home duties and had completed less formal education. Women who continued to drink were more likely to have drunk in previous pregnancies and during the preconception period. Nearly 40% of high risk women reported a negative comment in response to their drinking. One-third of women in the risky group were advised by a health professional not to drink alcohol. Women were most likely to drink in their own home or at the home of a friend. CONCLUSIONS Participatory research with women who drink while pregnant can assist in identifying potential intervention strategies that have resonance with this group and therefore more potential for creating behaviour change. Implications. The World Health Organization recognises, and has done for over 10 years, that alcohol use during pregnancy which results in Foetal Alcohol Spectrum Disorder is the leading cause of environmental-related birth defects and mental retardation in the Western world.

Abstract
AIM The study aims to provide paediatricians in Western Australia (WA) with educational resources (http://www.ichr.uwa.edu.au/alcoholandpregnancy) about the prevention of prenatal alcohol exposure and fetal alcohol spectrum disorder, and assess changes in their knowledge, attitudes and practice about fetal alcohol syndrome (FAS) and alcohol consumption in pregnancy. METHODS Following our 2004 survey of paediatricians, we developed and distributed educational resources to 159 paediatricians in WA in 2007. Six months later, we surveyed these paediatricians and compared their responses with results from 2004 using prevalence rate ratios (PRRs) and 95% confidence intervals (CIs). RESULTS Of 133 eligible paediatricians, 82 (61.7%) responded: 65.9% had seen the resources, of these 66.7% had used them and 29.6% said the resources had helped them change, or influenced their intent to change, their practice. There was no change in the proportion that knew all the essential features of FAS (18.3% in 2007; 20.0% in 2004) or had diagnosed FAS (58.5% in 2007; 58.9% in 2004). An increased proportion (75.6% in 2007; 48.9% in 2004) agreed that pregnant women should completely abstain from consuming alcohol (PRR 1.55, 95% CI 1.21-1.97). Only 21.7% (no increase from 2004) routinely asked about alcohol use when taking a pregnancy history. CONCLUSIONS We recommend that asking about alcohol use during pregnancy should be emphasised in paediatric training. Unless paediatricians' capacity to ask about alcohol consumption when taking a pregnancy history and to diagnose FAS is increased, FAS will remain under-diagnosed in Australia and opportunities for management, early intervention and prevention will be overlooked.

Abstract
INTRODUCTION Since the development of inclusion and integration, parents have increasingly become the major, and sometimes the only, carers of their children with disabilities. Many families speak of stress and frustration with service and community support, and some have turned to residential and specialised day care services to overcome challenges. The need for, and experiences of, such services needs to be examined not just in terms of the child but also in terms of family impact. METHOD The study involved interviewing parents on a 1:1 basis and in a focus group to examine the perceptions of family life, along with their later experience of full-time day and residential care. The children had multiple diagnoses of intellectual disability plus major challenging behaviour. RESULTS The results describe the major challenges facing families when the children spent most or all of their time at home. This contrasted starkly with the changes in perceived family life once the children were in residential care and day support. Improvements in behaviour of the children were noted and children began to return home for periods of time. Parent noted increased stability of family life, involvement of siblings in more normal community life and increased opportunities for spouses to function more effectively in one or more life domains. Family members perceived a major improvement in overall quality of life. DISCUSSION The results are consistent with findings in other family quality of life studies in terms of family experience, and the types of challenges faced when the child was at home, including when excluded from the regular education system. Extensive support in raising children is required by parents and without this there is a deleterious effect on family life. Many families experienced exclusion within their home communities. Full-time day and residential support were provided, allowing the family to function more effectively and later to provide a more natural home environment for the child. The article raises questions of policy concerning family well-being, as well as the needs of the child.

BACKGROUND Maternal alcohol consumption during pregnancy may potentially constitute a major public health concern in Canada but despite this, the available epidemiological data on both rates and predictors of alcohol consumption during pregnancy is limited. The present study assessed the prevalence and predictors of maternal alcohol consumption during pregnancy of women living in Canada from 2005-2006 who had a singleton live birth and whose child remained in their care 5-9 months following birth. Prevalence of maternal alcohol consumption was examined across the Canadian provinces. METHODS The analysis was based on the Maternity Experience Survey (MES), a population-based survey that assessed pregnancy, delivery and postnatal experiences of mothers and their children between November 2005 and May 2006. The main outcome variable assessed was ever drinking alcohol during pregnancy. The sample of mothers who drank during pregnancy consisted mainly of low to moderate level-alcohol drinkers (95.8%), while only 1.7% of the sample were heavy drinkers (>1 drink per day). Socio-economic factors, demographic factors, maternal characteristics, and pregnancy related factors that proved to be significant at the bivariate level were considered for a logistic regression analysis. Bootstrapping was performed to account for the complex sampling design. RESULTS Analysis of 5882 mothers, weighted to represent 72,767 Canadian women, found that 10.8% of women drank alcohol at some point during their pregnancies. This mainly reflects prevalence of low to moderate maternal alcohol consumption. Prevalence of drinking alcohol during pregnancy was 13.8% in Eastern-Central provinces, 7.8% in Western Provinces-British Columbia, 4.1% in Eastern-Atlantic provinces and 4.0% in Western-Prairie Provinces. Utilizing alcohol during gestation was significantly associated with several important factors including marital status, smoking status, reaction to the pregnancy and immigrant status. While being an immigrant to Canada appeared to confer a protective effect, women who have partners (odds ratio (OR)=2.00; 95% confidence interval (CI): 1.20, 3.31) and smoked during pregnancy (OR=1.54; 95% CI: 1.12, 1.87) were significantly more likely to drink alcohol during their pregnancies. Perhaps most importantly, pregnant women who reported indifference or being unhappy/very unhappy in regards to their pregnancies exhibited 1.89- and 2.5-fold increased risk of drinking alcohol during their pregnancies, respectively. CONCLUSION A number of important factors associated with maternal alcohol utilization during pregnancy have been identified, indicating areas where increased focus may serve to reduce maternal and pediatric morbidity and mortality.

Abstract
The concept of risk is especially salient to obstetric care. Unknown factors can still be responsible for peri-natal morbidity and mortality in circumstances that appeared to present little risk, while perfectly healthy infants are born in high-risk circumstances: a contradiction that patients and providers struggle with on a daily basis. With such contradictions comes the potential for the over-estimation of risk during pregnancy in order to assure a positive outcome. Understanding and addressing the estimation of risk during pregnancy requires acknowledging the history of obstetric risk in addition to understanding risk-related psychological theory. A relationship of trust between provider and patient is vital in addressing risk over-estimation, as is encouraging the development of self-efficacy in patients. Ultimately obstetric care is complex and efforts to avoid pre-natal risk exposure based on heightened perceptions of threat may do more harm than the perceived threat itself.

Abstract
There is controversy over whether increased breast-feeding duration has long-term benefits for language development. The current study examined whether the positive associations of breast feeding on language ability at age 5 years in the Western Australian Pregnancy (Raine) Cohort, were still present at age 10 years. The Raine Study is a longitudinal study of 2868 liveborn children recruited at approximately 18 weeks gestation. Breast-feeding data were based upon information prospectively collected during infancy, and were summarised according to four categories of breast-feeding duration: (1) never breast-fed, (2) breast-fed predominantly for <4 months, (3) breast-fed predominantly for 4-6 months, and (4) breast-fed predominantly for >6 months. Language ability was assessed in 1195 children at the 10 year follow-up (mean age = 10.58 years; standard deviation = 0.19) using the Peabody Picture Vocabulary Test - Revised (PPVT-R), which is based around a mean of 100 and a standard deviation of 15. Associations between breast-feeding duration and PPVT-R scores were assessed before and after adjustment for a range of sociodemographic, obstetric and psychosocial covariates. Analysis of variance revealed a strong positive association between the duration of predominant breast feeding and PPVT-R at age 10 years. A multivariable linear regression analysis adjusted for covariates and found that children who were predominantly breast-fed for >6 months had a mean PPVT-R score that was 4.04 points higher than children who were never breast-fed. This compared with an increase of 3.56 points at age 5 years. Breast feeding for longer periods in early life has a positive and statistically-independent effect on language development in middle childhood.

Abstract
BACKGROUND Teenage substance misuse and pregnancy are major public health problems in the UK, where the most recent figures on maternal deaths suggest that they have doubled among young substance misusers. In general, little is known about their pregnancy outcomes. AIMS The aims of this study were to describe the characteristics of a sample of teenage pregnant drug users in the UK, to examine their psychosocial risk and complicating factors at presentation, to evaluate adherence to current national guidelines and to assess the adequacy of guidelines in relation to identified characteristics. METHODS A six-year records survey of young people attending a specialist adolescent drug misuse service in the west midlands of the UK. RESULTS Ten pregnant adolescents were identified from records. These girls have had unstable or abusive experiences through childhood, half having other substance misusers in the family. All were with substantially older partners, who were also substance misusers. All had required a mental health assessment and 90% had a history of self-harm. There were no maternal or neonatal deaths, and only one girl had a miscarriage, but in four cases, the child had to be fostered. CONCLUSIONS To our knowledge, this is the first analysis of this kind in the UK. Available guidelines were followed, but our findings suggest that more detailed and comprehensive guidelines are required. Preventive measures through education are likely to be hampered by the early age at which these girls cease attending school.

Abstract
Preventing fetal alcohol spectrum disorders (FASDs) requires detection of in-pregnancy maternal risk drinking. The widely used T-ACE screen has been applied in various ways, although the impact of those different uses on effectiveness is uncertain. We examined relations among different T-ACE scoring criteria, maternal drinking, and child outcome. Self-reported across-pregnancy maternal drinking was assessed in 75 African-American women. The different T-ACE criteria used varied the level of drinking that defined tolerance (two or three drinks) and the total T-ACE score cut-points (two or three). Receiver operator curves and regression analysis assessed the significance of relations. Increasing the total T-ACE score cut-point to 3 almost doubled specificity in detecting risk drinking whereas maintaining adequate sensitivity, equivalent to that in the original report, and identified substantially more neurobehavioral deficits in children. Redefining tolerance at three drinks did not improve T-ACE effectiveness in predicting outcomes. This study is among the first to show the ability of an in-pregnancy T-ACE assessment to predict child neurodevelopmental outcome. In addition, increasing the total T-ACE score criterion (from 2 to 3) improved identification of non-drinking mothers and unaffected children with little loss in detection of drinkers and affected children. Efficient in-pregnancy screens for risk drinking afford greater opportunities for intervention that could prevent/limit FASDs.

Abstract
Detecting patterns of maternal drinking that place fetuses at risk for fetal alcohol spectrum disorders (FASDs) is critical to diagnosis, treatment, and prevention but is challenging because information on antenatal drinking collected during pregnancy is often insufficient or lacking. Although retrospective assessments have been considered less favored by many researchers due to presumed poor reliability, this perception may be inaccurate because of reduced maternal denial and/or distortion. The present study hypothesized that fetal alcohol exposure, as assessed retrospectively during child adolescence, would be related significantly to prior measures of maternal drinking and would predict alcohol-related behavioral problems in teens better than antenatal measures of maternal alcohol consumption. Drinking was assessed during pregnancy, and retrospectively about the same pregnancy, at a 14-year follow-up in 288 African-American women using well-validated semistructured interviews. Regression analysis examined the predictive validity of both drinking assessments on pregnancy outcomes and on teacher-reported teen behavior outcomes. Retrospective maternal self-reported drinking assessed 14 years postpartum was significantly higher than antenatal reports of consumption. Retrospective report identified 10.8 times more women as risk drinkers (≥ one drink per day) than the antenatal report. Antenatal and retrospective reports were moderately correlated and both were correlated with the Michigan Alcoholism Screening Test. Self-reported alcohol consumption during pregnancy based on retrospective report identified significantly more teens exposed prenatally to at-risk alcohol levels than antenatal, in-pregnancy reports. Retrospective report predicted more teen behavior problems (e.g., attention problems and externalizing behaviors) than the antenatal report. Antenatal report predicted younger gestational age at birth and retrospective report predicted smaller birth size; neither predicted teen IQ. These results suggest that if only antenatal, in-pregnancy maternal report is used, then a substantial proportion of children exposed prenatally to risk levels of alcohol might be misclassified. The validity of retrospective assessment of prior drinking during pregnancy as a more effective indicator of prenatal exposure was established by predicting more behavioral problems in teens than antenatal report. Retrospective report can provide valid information about drinking during a prior pregnancy and may facilitate diagnosis and subsequent interventions by educators, social service personnel, and health-care providers, thereby reducing the life-long impact of FASDs.

Abstract
BACKGROUND Prenatal exposure to alcohol has a variety of morphologic and neurobehavioral consequences, yet more than 10% of women continue to drink during pregnancy, placing their offspring at risk for fetal alcohol spectrum disorders (FASD). Identification of at-risk pregnancies has been difficult, in part, because the presence and severity of FASD are influenced by factors beyond the pattern of alcohol consumption. Establishing maternal characteristics, such as maternal age, that increase the risk of FASD is critical for targeted pregnancy intervention. METHODS We examined the moderating effect of maternal age on measures of attention in 462 children from a longitudinal cohort born to women with known alcohol consumption levels (absolute ounces of alcohol per day at conception) who were recruited during pregnancy. Analyses examined the impact of binge drinking, as average ounces of absolute alcohol per drinking day. Smoking and use of cocaine, marijuana, and opiates were also assessed. At 7 years of age, the children completed the Continuous Performance Test, and their teachers completed the Achenbach Teacher Report Form. RESULTS After controlling for covariates, stepwise multiple regression analyses revealed a negative relation between levels of prenatal binge drinking and several measures of attention. The interaction between alcohol consumption and maternal age was also significant, indicating that the impact of maternal binge drinking during pregnancy on attention was greater among children born to older drinking mothers. CONCLUSION These findings are consistent with previous findings that children born to older alcohol-using women have more deleterious effects of prenatal alcohol exposure on other neurobehavioral outcomes.

Abstract
OBJECTIVE To assess women's compliance with different Australian guidelines on alcohol intake during pregnancy and examine factors that might influence compliance. DESIGN, SETTING AND PARTICIPANTS We analysed prospective, population-based data on women aged 22-33 years who were pregnant before October 2001, when guidelines recommended zero alcohol (n = 419), or were first pregnant after October 2001, when guidelines recommended low alcohol intake (n = 829). Data were obtained from surveys conducted in 1996, 2000, 2003 and 2006 as part of the Australian Longitudinal Study on Women's Health. MAIN OUTCOME MEASURES Relative risks (RRs) for zero alcohol intake, low alcohol intake and compliance with alcohol guidelines, estimated by a modified Poisson regression model with robust error variance. RESULTS About 80% of women consumed alcohol during pregnancy under zero and low alcohol guidelines. Compliance with zero alcohol guidelines or low alcohol guidelines (up to two drinks per day and less than seven drinks per week) was the same for women who were pregnant before October 2001 and women who were first pregnant after October 2001 (20% v 17% for compliance with zero alcohol guidelines, P > 0.01; 75% v 80% for compliance with low alcohol guidelines, P > 0.01). Over 90% of women drank alcohol before pregnancy and prior alcohol intake had a strong effect on alcohol intake during pregnancy, even at low levels (RR for zero alcohol, 0.21 [95% CI, 0.16-0.28]; RR for low alcohol, 0.91 [95% CI, 0.86-0.96]). RR for compliance with guidelines was 3.54 (95% CI, 2.85-4.40) for women who were pregnant while low alcohol intake was recommended, compared with those who were pregnant while zero alcohol guidelines were in place. CONCLUSION The October 2001 change in alcohol guidelines does not appear to have changed behaviour. Risks associated with different levels of alcohol intake during pregnancy need to be clearly established and communicated.

Abstract
BACKGROUND There is accumulating evidence for a link between maternal stress during pregnancy and later behavioural and emotional problems in children. Little research has examined other developmental outcomes. AIM To determine the effect of maternal stress during pregnancy on offspring language ability in middle childhood. STUDY DESIGN Longitudinal pregnancy cohort-study. SUBJECTS A total of 2900 mothers were recruited prior to the 18th week of pregnancy, delivering 2868 live births. The language ability of just under half of the offspring cohort (n=1309; 45.6% of original sample) was assessed in middle childhood (Mean age=10;7, Standard deviation=0;2, range: 9;5-11;11). OUTCOME MEASURES Language ability was measured using the Peabody Picture Vocabulary Test-Revised (PPVT-R). The main predictor variable was the frequency of 10 typically 'stressful' life events experienced by mothers during early and/or late pregnancy. Children were allocated to four groups according to whether they were exposed to high maternal stress (>or=2 life events) during early pregnancy only, late pregnancy only, both, or neither. RESULTS Mixed-effects regression analyses revealed no association between the maternal experience of two or more stressful life events at any time-point during pregnancy and PPVT-R scores. Repeating the regression analyses with more lenient (>or=1 life events) or strict (>or=3 life events) thresholds for defining high-levels of maternal stress did not alter the pattern of findings. CONCLUSIONS Maternal experience of typically stressful life events during pregnancy has a negligible effect on vocabulary development to middle childhood.

Abstract
BACKGROUND the Australian National Health and Medical Research Council (NHMRC) recently revised its guidelines for alcohol consumption during pregnancy and breast feeding, moving from a recommendation of minimising intake to one of abstinence. Women are potentially exposed to a variety of messages about alcohol and pregnancy, including from the media and social contacts, and are likely to see midwives as the source of expert advice in understanding these contradictory messages. OBJECTIVE to explore the advice that midwives believe they give to pregnant women about alcohol consumption, and the advice that pregnant women believe they receive; the knowledge and attitudes of both groups regarding alcohol consumption and the consistency with the NHMRC guidelines; and the receptivity and comfort of both groups in discussing alcohol consumption in the context of antenatal appointments. DESIGN individual semi-structured interviews with midwives and pregnant women. SETTING face-to-face interviews with midwives and telephone interviews with pregnant women were conducted in two regional areas of New South Wales in 2008-2009. PARTICIPANTS 12 midwives and 12 pregnant women. FINDINGS midwives and pregnant women consistently agreed that conversations about alcohol are generally limited to brief screening questions at the first visit, and the risks are not discussed or explained (except for high-risk women). KEY CONCLUSIONS both groups expressed comfort with the idea of discussing alcohol consumption, but lacked knowledge of the risk and recommendation, and it appears that this opportunity to provide women with information is under-utilised. IMPLICATIONS FOR PRACTICE there is a need to provide midwives with accurate information about the risks of alcohol consumption during pregnancy and effective communication tools to encourage them to discuss the risks and recommendations with their patients.

Abstract
Balance problems in childhood have known adverse psychosocial associations such as poorer quality of life and lower educational achievement. Previous longitudinal studies have documented an adverse effect of prenatal alcohol exposure on a variety of neurodevelopmental outcomes and so an effect on balance would seem plausible. This is supported by a previous laboratory study that found that rats exposed to ethanol in utero have dysfunctional balance and gait. The present study is a systematic review of the current evidence on the effects of maternal alcohol use during pregnancy on offspring balance in childhood. A search strategy was devised and applied in the CENTRAL database (Cochrane Collaboration). Prospective longitudinal studies were then sought using databases including Medline, EMBASE, PsychInfo, CINAHL and AMED. In addition, citations in relevant published papers and books were followed up and experts in the field were contacted. No relevant human experimental studies were found. Four longitudinal studies were found to have assessed balance in preschool children. Only one of these studies suggested strong or substantial effects of alcohol exposure on balance-related outcomes. However, this study appeared the most methodologically robust. In conclusion, at present, there is limited evidence on the possible effects of alcohol exposure on childhood balance.

Abstract
While Australian legislation does not currently require health warning labels on alcohol products, several medical and advocacy organizations have been campaigning for their mandatory inclusion. The current study examines the attitudes and opinions of university students (a particularly high-risk group) relating to these messages, and the likelihood of such labeling influencing personal behaviors, in order to establish whether the introduction of these labels is likely to be effective. Alcohol warning labels have the potential to influence behaviors of adolescents and young adults, especially if modifications are made to the content and format of these—suggestions are given in this article. Finally, results of this research indicate that such health messages must be integrated with other educational measures and strategies aiming to internalize alcohol risk information by changing beliefs and, ultimately, behaviors.

Abstract
Animal models of fetal alcohol spectrum disorder (FASD) have been used to demonstrate the specificity of alcohol's teratogenic effects and some of the underlying changes in the central nervous system (CNS) and, more recently, to explore ways to ameliorate the effects of alcohol. The main point of this review is to highlight research findings from the animal literature which point to the impact of the social context or social behavior on the effect(s) of alcohol exposure during development, and also to point to research questions about the social environment and effects of prenatal alcohol exposure that remain to be answered. Alcohol exposure during early development alters maternal responding to the exposed pup in a variety of ways and the alteration in maternal responding could alter later stress responsivity and adult maternal and social behavior of the exposed offspring. Environmental enrichment and voluntary exercise have been shown to ameliorate some of alcohol's impact during development, but the roles of enhanced social interactions in the case of enrichment and of social housing during voluntary exercise need to be more fully delineated. Similarly, the role of social context across the lifespan, such as social housing, social experiences, and contact with siblings, needs further study. Because of findings that alcohol during development alters DNA methylation patterns and that there are alterations in the maternal care of the alcohol-exposed offspring, epigenetic effects and their relationship to social behavior in animal models of FASD are likely to become a fruitful area of research. Because of the simpler social behavior and the short lifespan of rodents, animal models of FASD can be useful in determining how the social context impacts the effects of alcohol exposure during development.

Abstract
AbstractObjectiveTo document nutritional status and health behaviours of young indigenous women of childbearing age in rural communities in north Queensland.DesignCross-sectional survey of 424 Aboriginal and 232 Torres Strait Islander (TSI) women aged 15–34 years, conducted in twenty-three rural and remote communities of far north Queensland in 1999–2000, with follow-up of a smaller cohort (n132) in 2006–2007.Main outcome measuresWeight, waist circumference, intake of fruit and vegetables, smoking, alcohol intake, fasting blood glucose, blood pressure, HDL cholesterol, γ-glutamyltransferase, red cell folate (RCF), interval weight and waist gain and incidence of diabetes.ResultsForty-one per cent of Aboriginal and 69 % of TSI had central obesity, 62 % were smokers, 71 % drank alcohol regularly and of those, 60 % did so at harmful levels. One third of Aboriginal and 16 % of TSI women had very low RCF levels. In the group followed up, there was a mean annual waist gain of 1·6 cm in Aboriginal women and 1·2 cm in TSI, 0·5 kg/m2in BMI and 1·5 kg in weight. Incidence of new type 2 diabetes mellitus in this cohort was 29·1 per 1000 person-years (py) (95 % CI 14·0, 52·8) in Aboriginal women and 13·9 per 1000 py (95 % CI 5·6, 28·5) among TSI.ConclusionsHigh prevalence and incidence of central obesity and diabetes, poor nutrition, high rates of alcohol use and tobacco smoking together with young maternal age, provide a poor intra-uterine environment for many indigenous Australian babies, and contribute to high perinatal morbidity and future disability. Community level interventions to improve pre-pregnancy nutrition and health behaviours in young women are urgent.

Abstract
Alcohol policies have potentially far-reaching impacts on risky sexual behavior, prenatal health behaviors, and subsequent outcomes for infants. After finding initial evidence in the National Longitudinal Survey of Youth (NLSY) that changes in the minimum legal drinking age (MLDA) are related to prenatal drinking, we examine whether the drinking age influences birth outcomes. Using data from the National Vital Statistics (NVS) for the years 1978-1988, we find that a drinking age of 18 is associated with adverse outcomes among births to young mothers-including higher incidences of low birth weight and premature birth, but not congenital anomalies. The effects are largest among black women. We also report evidence that the MLDA laws alter the composition of births that occur. In states with lenient drinking laws, young black mothers are less likely to report paternal information on the birth certificate, particularly in states with restrictive abortion policies. The evidence suggests that lenient drinking laws generate poor birth outcomes in part because they increase the number of unplanned pregnancies.

Abstract
OBJECTIVE The aim of this study was to investigate the association of dose and timing of prenatal alcohol exposure with early language acquisition. METHODS We examined language delay in a randomly selected, population-based sample of Western Australian children born in 1995-1996 whose mothers had agreed to participate in a longitudinal study on health-related behaviors and who had completed the 2-year questionnaire (N = 1739). Information on alcohol consumption was collected at 3 months after birth for four periods; the three months pre-pregnancy and for each trimester separately. Prenatal alcohol exposure was grouped into none, low, moderate-heavy and binge (>5) based on the total quantity consumed per week, quantity consumed per occasion, and frequency of consumption. The communication scale from the Ages & Stages Questionnaire was used to evaluate language delay. Logistic regression analysis was used to generate odds ratios and 95% confidence intervals, adjusted for confounding factors. RESULTS There was no association between low levels of alcohol consumption and language delay at any time period, although there was a nonsignificant 30% increase in risk when moderate-to-heavy levels of alcohol were consumed in the third trimester. Children exposed to a binge pattern of maternal alcohol consumption in the second trimester had nonsignificant, three-fold increased odds of language delay, with a similar estimate following third trimester alcohol exposure after controlling for covariates. CONCLUSIONS This study did not detect an association between low levels of prenatal alcohol exposure and language delay when compared with women who abstained from alcohol during pregnancy. A nonsignificant threefold increase in the likelihood of language delay was seen in children whose mothers binged during late pregnancy. However, the small numbers of women with a binge-drinking pattern in late pregnancy limited the power of this study; studies analyzing larger numbers of children exposed to binge drinking in late pregnancy are needed.

Abstract
This study aims to test the hypothesis that moderate maternal alcohol and tobacco use in pregnancy is associated with intelligent quotient (IQ) scores in childhood through intrauterine mechanisms. We conducted parental-offspring comparisons between the associations of tobacco and alcohol consumption with child's IQ in the Avon Longitudinal Study of Parents and Children. Analyses were conducted on 4332 participants with complete data on maternal and paternal use of alcohol and tobacco at 18 wk gestation, child's IQ and a range of confounders. IQ was measured at child age 8 with the Weschler Intelligence Scale for Children (WISC-III). We used multivariable linear and logistic regression to estimate mean differences and 95% confidence intervals in IQ scores across the exposure categories and computed f statistics to compare maternal and paternal associations. In fully adjusted models, there was no strong statistical evidence that maternal alcohol and tobacco consumption during pregnancy were associated with childhood IQ with any greater magnitude than paternal alcohol and tobacco consumption (also assessed during their partners' pregnancy). Our findings suggest that the relationship between maternal moderate alcohol and tobacco use in early pregnancy and childhood IQ may not be explained by intrauterine mechanisms.

Abstract
New draft alcohol guidelines for Australia state that, for pregnant women and women planning pregnancy, 'no drinking is the safest option'. One of the best known adverse effects of alcohol exposure on the fetus is the fetal alcohol syndrome. Others include alcohol-related birth defects, alcohol-related neurodevelopmental disorders and increased risks of miscarriage, stillbirth, intrauterine growth restriction, preterm birth and low birthweight. Over half of Australian women consume alcohol during pregnancy. Obstetricians have a pivotal role in advising women of the effects of alcohol on the fetus and reducing fetal exposure.

Abstract
Alcohol Denat. is the generic term used by the cosmetics industry to describe denatured alcohol. Alcohol Denat. and various specially denatured (SD) alcohols are used as cosmetic ingredients in a wide variety of products. Many denaturants have been previously considered, on an individual basis, as cosmetic ingredients by the Cosmetic Ingredient Review (CIR) Expert Panel, whereas others, including Brucine and Brucine Sulfate, Denatonium Benzoate, and Quassin, have not previously been evaluated. Quassin is a bitter alkaloid obtained from the wood of Quassia amara. Quassin has been used as an insect antifeedant and insecticide and several studies demonstrate its effectiveness. At oral doses up to 1000 mg/kg using rats, Quassin was not toxic in acute and short-term tests, but some reversible piloerection, decrease in motor activity, and a partial loss of righting reflex were found in mice at 500 mg/kg. At 1000 mg/kg given intraperitoneally (i.p.), all mice died within 24 h of receiving treatment. In a cytotoxicity test with brine shrimp, 1 mg/ml of Quassin did not possess any cytotoxic or antiplasmodial activity. Quassin administered to rat Leydig cells in vitro at concentrations of 5–25 ng/ml inhibited both the basal and luteinizing hormone (LH)-stimulated testosterone secretion in a dose-related fashion. Quassin at doses up to 2.0 g/kg in drinking water using rats produced no significant effect on the body weights, but the mean weights of the testes, seminal vesicles, and epididymides were significantly reduced, and the weights of the anterior pituitary glands were significantly increased. The sperm counts and levels of LH, follicle-stimulating hormone (FSH), and testosterone were significantly lower in groups treated with Quassin. Brucine is a derivative of 2-hydroxystrychnine. Swiss-Webster mice given Brucine base, 30 ml/kg, had an acute oral LD50 of 150 mg/kg, with central nervous system depression followed by convulsions and seizures in some cases. In those animals that died, respiratory arrest was the cause. The acute i.p. LD50 for 15 ml/kg of Brucine base was 62.0 mg/kg, with central nervous system depression prior to the onset of convulsions, just as with oral Brucine. The acute intravenous (i.v.) LD50 was 12.0 mg/kg. Brucine was nonmutagenic in an Ames assay at levels up to 6666 ìg/plate, with and without metabolic activation. In a repeat-insult patch test, for a hair care product containing 47% SD Alcohol 40 (95%), it was reported that Brucine Sulfate may be considered a nonprimary irritant and a nonprimary sensitizer. Three different sunscreen products (35% SD Alcohol 40-B, 72.4% SD Alcohol 40, and 74.5% SD Alcohol 40) did not show any signs of photoallergy in human subjects. Also, these three formulas did not exhibit any evidence of phototoxicity in humans. Denatonium Benzoate is a bitter substance detectable at a concentration of 10 ppb, discernibly bitter at 50 ppb, and unpleasantly bitter at 10 ppm. The distribution of topically applied lidocaine, a topical anesthetic chemically related to Denatonium Benzoate demonstrated that virtually no lidocaine appears in the plasma, suggesting that the larger Denatonium Benzoate molecule also would have little or no systemic exposure. Denatonium Benzoate (0.1%) did not show adverse effects in 10 rats in an acute inhalation toxicity test and 0.005% to 0.05% was nonirritating to ocular mucosa in 6 albino rabbits. The acute oral LD50 for the male rats was 640 mg/kg and for females, 584 mg/kg. The LD50 for the male rabbits was 508 mg/kg and for the female rabbits, 640 mg/kg. In two chronic toxicity studies, Denatonium Benzoate was administered (by gavage) at 1.6, 8, and 16 mg/kg/day, one using cynomologus monkeys and the other rats, resulted in no compound-related toxicity. The toxicity of SD Alcohols has also been tested, with implications for the particular denaturant used. An irritation test of 55.65% SD Alcohol 40-B denatured with Denatonium Benzoate using rabbits produced minimal effects. A spray formula containing 12% SD Alcohol 40-B was found to be nonirritating when evaluated for vaginal mucosal irritation in New Zealand white rabbits. Cosmetic formulations containing SD Alcohol 40-B (denatured with Denatonium Benzoate) were not sensitizers in repeated insult patch tests. A gel formula containing 29% SD Alcohol 40-B and a spray liquid containing 12% SD Alcohol 40-B did not induce photoallergy, dermal sensitization, or phototoxic response in human subjects. Although the absorption of ethanol (aka Alcohol for purposes of cosmetic ingredient labeling) occurs through skin, ethanol does not appear to affect the integrity of the skin barrier nor reach a very high systemic concentration following dermal exposure. Ethanol may be found in the bloodstream as a result of inhalation exposure and ingestion. Topically applied, ethanol can act as a penetration enhancer. Most of the systemic toxicity of ethanol appears to be associated with chronic abuse of alcohol. Although ethanol is denatured to make it unfit for consumption, there have been reports of intentional and unintentional consumption of products containing denatured alcohol. Ethanol is a reproductive and developmental toxicant. Ethanol is genotoxic in some test systems and it has been proposed that the genotoxic effects of ethanol are mediated via its metabolite, acetaldehyde. A brief summary is provided of the effects of chronic ingestion of alcohol including intoxication, liver damage, brain damage, and possible carcinogenicity. The CIR Expert Panel recognizes that certain ingredients in this group are reportedly used in a given product category, but the concentration of use is not available. Because dermal application or inhalation of cosmetic products containing these ingredients will not produce significant systemic exposure to ethanol, the CIR Expert Panel concluded that safety of the ingredients should be predicated on the safety of the denaturants used. The Panel considered that the adverse effects knownto be associated with Alcohol ingestion included in this safety assessment do not suggest a concern for Alcohol Denat. or SD Alcohols because of the presence of the denaturants, which are added for the express purpose of making the Alcohol unpotable. The CIR Expert Panel has previously conducted safety assessments of t-Butyl Alcohol, Diethyl Phthalate, Methyl Alcohol, Salicylic Acid, Sodium Salicylate, and Methyl Salicylate, in which each was affirmed safe or safe with qualifications. Given their use as denaturants are at low concentrations of use in Alcohol, the CIR Expert Panel determined that Alcohol Denat. denatured with t- Butyl Alcohol, Diethyl Phthalate, Methyl Alcohol, Salicylic Acid, Sodium Salicylate, and Methyl Salicylate is safe as used in cosmetic formulations with no qualifications. Likewise, because they are denatured with either t-Butyl Alcohol, Diethyl Phthalate, or Methyl Alcohol, SD Alcohols 3-A, 30, 39-B, 39-C, and 40-C all are considered safe as used. The Panel considered the available data for Denatonium Benzoate and SD Alcohol 40-B to be sufficient to support the safety of these ingredients in cosmetics. Denatonium Benzoate is sufficiently bitter that it is an effective denaturant at only 0.0006%. The Panel recognized that data on dermal penetration of Denatonium Benzoate were not available, but considered that the available data on lidocaine, a smaller structurally related chemical, indicates that dermal exposure does not result in measurable systemic exposure. The available data, however, were not sufficient to support the safety of Quassin, Brucine, and Brucine Sulfate, Alcohol Denat. denatured with those denaturants, or SD Alcohol 39 and SD Alcohol 40 (SD Alcohols denatured with Quassin, Brucine, and/or Brucine Sulfate), and in order for the Expert Panel to reach a conclusion for these denaturants, additional data are needed.

Abstract
Intrauterine growth restriction (IUGR) is one of the key features of fetal alcohol syndrome (FAS), and IUGR can be mediated by impaired placentation. Insulin-like growth factors (IGF) regulate placentation due to stimulatory effects on extravillous trophoblasts, which are highly motile and invasive. Previous studies demonstrated that extravillous trophoblasts express high levels of aspartyl-(asparaginyl) beta-hydroxylase (AAH), a gene that is regulated by IGF and has a critical role in cell motility and invasion. The present study examines the hypothesis that ethanol impaired placentation is associated with inhibition of AAH expression in trophoblasts. Pregnant Long Evans rats were fed isocaloric liquid diets containing 0% or 37% ethanol by caloric content. Placentas harvested on gestation day 16 were used for histopathological, mRNA, and protein studies to examine AAH expression in relation to the integrity of placentation and ethanol exposure. Chronic ethanol feeding prevented or impaired the physiological conversion of uterine vessels required for expansion of maternal circulation into placenta, a crucial process for adequate placentation. Real-time quantitative RT-PCR analysis demonstrated significant reductions in IRS-1, IRS-2, and significant increases in IGF-II and IGF-II receptor mRNA levels in ethanol-exposed placentas. These abnormalities were associated with significantly reduced levels of AAH expression in trophoblastic cells, particularly within the mesometrial triangle (deep placental bed) as demonstrated by real time quantitative RT-PCR, Western blot analysis, ELISA, and immunohistochemical staining. Ethanol-impaired placentation is associated with inhibition of AAH expression in trophoblasts. This effect of chronic gestational exposure to ethanol may contribute to IUGR in FAS.

Abstract
OBJECTIVE To establish the prevalence of fetal alcohol syndrome (FAS) in Victoria through the Victorian Birth Defects Register (VBDR). METHODS A sample of live births from 1995-2002 was selected from the Victorian Perinatal Data Collection and VBDR based on reported microcephaly, FAS or maternal use of alcohol during pregnancy. Following ethics approval, medical records of mother and child were requested for 117 births. One hundred and nine of these were accessed and examined for factors related to FAS. Records were categorised as FAS, possible FAS, unable to categorise, or not FAS. RESULTS From the VBDR the prevalence was calculated at 0.006 per 1,000 live births. Four additional possible cases of FAS increased this to 0.014 per 1,000 live births. Six cases were defined as 'unable to categorise' as alcohol use was unknown but other features of FAS were evident. Including these cases, plus five where some low-level alcohol use was reported, increased the prevalence to 0.03 per 1,000 live births. Twenty-eight per cent of the audit population and 39% of the microcephalic cases had no information about maternal alcohol use recorded in the antenatal or babies' records. CONCLUSION AND IMPLICATIONS The audit of medical records provided additional information regarding FAS prevalence in Victoria. This prevalence ranges from 0.01 to 0.03 per 1,000 live births. To accurately assess the extent of the problem, there needs to be improved reporting of alcohol use in pregnancy and a system in place to report cases diagnosed during and beyond the perinatal period to the VBDR.

Abstract
Canada's Aboriginal peoples face a number of social and health issues. Research shows that Aboriginal youths are over-represented in the criminal justice system and youth forensic psychiatric programmes. Within the literature on sex offending youth, there appears to be no published data available to inform clinicians working with adjudicated Aboriginal youth. Therefore, the present study examines the background, offence characteristics, and criminal outcomes of Aboriginal (n = 102) and non-Aboriginal (n = 257) youths who engaged in sexual offending behaviour and were ordered to attend a sexual offender treatment programme in British Columbia between 1985 and 2004. Overall, Aboriginal youths were more likely than non-Aboriginal youths to have background histories of fetal alcohol spectrum disorders (FASD), substance abuse, childhood victimization, academic difficulties, and instability in the living environment. Both Aboriginal and non-Aboriginal youths had a tendency to target children under 12-years-old, females, and non-strangers. Aboriginal youths were more likely than non-Aboriginal youths to use substances at the time of their sexual index offence. Outcome data revealed that Aboriginal youths were more likely than their non-Aboriginal counterparts to recidivate sexually, violently, and non-violently during the 10-year follow-up period. Furthermore, the time between discharge and commission of all types of re-offences was significantly shorter for Aboriginal youths than for non-Aboriginal youths. Implications of these findings are discussed with regards to the needs of Aboriginal youth and intervention.

Abstract
It is well accepted that heavy alcohol consumption during pregnancy is a risk factor for fetal alcohol spectrum disorder, but research findings for exposure to low to moderate alcohol levels during pregnancy are equivocal, allowing a range of interpretations. The 2001 guideline from the National Health and Medical Research Council (NHMRC) for low-risk drinking for "women who are pregnant or might soon become pregnant" recommends fewer than seven standard drinks per week, and no more than two standard drinks on any one day. This position has polarised health professional and consumer opinion in Australia. The NHMRC guidelines on alcohol are scheduled for review in 2007. We surveyed the alcohol and pregnancy policies and clinical practice guidelines of Australia and six other English-speaking countries to identify current policy. Documents were obtained through Internet searches and direct contact with the relevant organisations. The policies and guidelines varied both across and within countries, and the NHMRC guideline, while not universally supported in Australia, is in step with the policies of the United Kingdom and Canada. Research is needed to elucidate the true association between low to moderate alcohol consumption and fetal harm, the impact of different policies on rates of maternal alcohol consumption during pregnancy, and any untoward outcomes of an abstinence message, to inform and underpin future policy development in Australia.

Abstract
An understanding of the epidemiology of alcohol and drug use in young women is important for three main reasons: (1) to appreciate that substance use, misuse, harmful use and dependence are associated with considerable mortality and physical and psychological morbidity; (2) to understand the nature and extent of these problems and the likely impact on the fetus, neonate and infant through childhood to adolescence; and (3) to utilize this information as part of a needs assessment to develop effective services, which detect problems and deliver appropriate interventions. Although abstention rates are consistently higher among women than men in general, substance misuse is increasing in young women. Simultaneously, there is great variability in prevalence rates in different countries, regions of countries and in different ethnic groups. This can be explained in part by differences in definitions, measurement techniques, availability, price, social acceptability, seizure and arrest policies, and in patterns and modes of use. During pregnancy, up to 15% of women may be using alcohol and about 5% may be using illicit drugs. The proportion of women using substances is less at term than in the early stages of pregnancy. Despite this, substance use rises sharply in the first 6 months postpartum. Detection of substance use in obstetric units is low but perinatal substance misuse intervention reduces adverse neonatal outcomes. On the basis of the relatively high rate of substance use disorders during pregnancy, effective screening and intervention strategies should be implemented.

Abstract
OBJECTIVE The purpose of this analysis was to track the estimated prevalence of binge drinking for the years 2001-2003 among U.S. women of childbearing age in order to inform ongoing efforts to prevent alcohol-exposed pregnancies. METHOD A total of 58,431, 64,181, and 65,678 women aged 18-44 for the years 2001, 2002, and 2003, respectively, participated in the Centers for Disease Control and Prevention's (CDC) Behavioral Risk Factor Surveillance System (BRFSS) survey. The estimated binge drinking prevalence for each survey year and changes in these estimates for the entire survey period were calculated for these women. RESULTS The estimated binge drinking prevalence among childbearing-age women 18-44 years for the years 2001, 2002, and 2003 was 11.9%, 12.4%, and 13.0%, respectively. The estimated number of childbearing-age women who engaged in binge drinking rose from 6.2 million in 2001 to 7.1 million in 2003, an increase of 0.9 million. CONCLUSION The results of this analysis provide support for enhancing efforts among healthcare providers to identify and intervene with childbearing-age women who engage in alcohol use that can increase their risks for various health problems, including an alcohol-exposed pregnancy.

Abstract
OBJECTIVES Maternal alcohol use is a leading preventable cause of neurobehavioral and developmental abnormalities in children. This study examines the patterns and average volume of alcohol use among U.S. women of childbearing age in order to identify subgroups of high-risk women for selective intervention. METHODS A sample of 188,290 women aged 18-44 years participated in the Centers for Disease Controls and Prevention (CDC)'s Behavioral Risk Factor Surveillance System (BRFSS) survey during the period of 2001-2003. Reported alcohol use patterns and average volume were examined for pregnant and nonpregnant women. Efforts were made to evaluate and characterize women who practiced various levels of binge drinking. RESULTS The results showed that approximately 2% of pregnant women and 13% of nonpregnant women in the United States engaged in binge drinking during the period of 2001-2003. Among the estimated average of 6.7 million women of childbearing age overall who engaged in binge drinking during the period, approximately 28.5% women also reported consuming an average of 5 drinks or more on typical drinking days, or about 21.4% women consumed at least 45 drinks on average in a month. Larger proportions of binge drinkers with high usual quantity of consumption were found among women of younger ages (18-24 years) or current smokers. CONCLUSIONS Future prevention efforts should include strategies that combine health messages and encourage women of childbearing age, with particular emphasis on women 18-24 years, to avoid alcohol and tobacco use, and take multivitamins and folic acid daily for better pregnancy outcomes. Other efforts must also include broad-based implementation of screening and brief intervention for alcohol misuse in primary and women's health care settings.

Abstract
BACKGROUND A range of adverse birth outcomes is associated with heavy prenatal alcohol exposure. AIM To examine the effects of moderate levels of alcohol consumption during pregnancy on children's intellectual ability, learning and attention at 14 years of age. STUDY DESIGN AND SUBJECTS The Mater-University of Queensland Study of Pregnancy involves a prospective birth cohort of 7223 singletons whose mothers were enrolled at the first antenatal visit. At 14 years, 5139 mothers and adolescents completed attentional and learning questionnaires, and 3731 adolescents completed psychometric assessments. OUTCOME MEASURES For adolescents, the Wide Range Achievement Test--Revised (WRAT-R) and Raven's Standard Progressive Matrices Test (Raven's) were administered. Mothers completed the Child Behaviour Checklist (CBCL) and adolescents completed the Youth Self Report (YSR). Learning was assessed by a series of questions in the mother and adolescent questionnaires. Maternal measures included the quantity and frequency of alcohol consumption, and the extent of binge drinking. RESULTS For consumption of <1 glass/day in early or late pregnancy, there was no association with any attention, learning or cognitive outcomes. The strongest estimates of effect were found among those consuming > or =1 glasses/day. Exposure in late pregnancy was associated with increased prevalence of overall learning difficulty in the unadjusted, although not the adjusted analysis. Binge drinking was associated with a higher prevalence of Raven's score <85 (1 standard deviation). CONCLUSIONS Although a number of study limitations need to be considered, the results suggest that consumption at the level of <1 drink/day does not lead to adverse outcomes in relation to attention, learning and cognitive abilities, as measured in the current research.

Abstract
OBJECTIVES Fetal alcohol syndrome (FAS) is a collection of signs and symptoms seen in children exposed to alcohol in the prenatal period. It is characterized mainly by a distinct pattern of craniofacial malformations, physical and mental retardation. However, with the increased incidence of FAS, there is a great variation in the clinical features of FAS. DESIGN Narrative review. RESULTS This review describes data from clinical and experimental studies, and in vitro models. Experimental studies have shown that alcohol has a direct toxic effect on the ectodermal and mesodermal cells of the developing embryo, particularly in the cells destined to give rise to dentofacial structures (i.e. cranial neural crest cells). Other effects, such as, abnormal pattern of cranial and mandibular growth and altered odontogenesis are described in detail. The exact mechanism by which alcohol induces its teratogenic effects remains still unknown. The possible mechanisms are outlined here, with an emphasis on the developing face and tooth. Possible future research directions and treatment strategies are also discussed. CONCLUSION Early identification of children affected by prenatal alcohol exposure leads to interventions, services, and improved outcomes. FAS can be prevented with the elimination of alcohol consumption during pregnancy. We need to provide education, target high-risk groups, and make this issue a high priority in terms of public health.

Abstract
AIM This paper presents an overview of current literature relating to over-the-counter and herbal preparations use, with a focus on pregnancy. BACKGROUND Internationally, there has been a shift towards self-medication through over-the-counter release of many prescription-category drugs and wider acceptance and use of herbal preparations. The general community perception that these preparations are safe may lead to inappropriate use, especially during pregnancy. METHOD A range of databases was searched to identify papers addressing 'over-the-counter preparations/medications', 'non-prescription medications', 'herbal preparations' and 'pregnancy', including Medline, Cumulative Index to Nursing, Allied Health Literature, Proquest and Sciencedirect. Midwifery, nursing and scientific papers published from 2000 onwards were included, along with a small number of scientific papers published from 1995 onwards, and some key textbooks to clarify the definitions. FINDINGS Pregnant women use a range of over-the-counter preparations, including analgesics, antihistamines, antacids and a variety of herbal preparations. However, in many cases, it is unclear whether their use is actually safe in the short- or long-term for mother or baby, owing to an inadequate evidence-base to support the use of these preparations during pregnancy. CONCLUSION While there is extensive literature on the use of over-the-counter preparations generally, less is available about their use in pregnancy. Further research is needed to explore the prevalence of use and effects of these preparations in pregnancy and neonatal outcomes, and to support midwives and nurses in harm minimization through the promotion of informed risk-avoidance behaviours.
