Abstract
In Australia, there is a significant gap between health outcomes in Indigenous and non-Indigenous children, which may relate to inequity in health service provision, particularly in remote areas. The aim was to conduct a scoping review to identify publications in the academic and grey literature and describe 1) Existing health services for Indigenous children in remote Australia and service use, 2) Workforce challenges in remote settings, 3) Characteristics of an effective health service, and 4) Models of care and solutions. Electronic databases of medical/health literature were searched (Jan 1990 to May 2021). Grey literature was identified through investigation of websites, including of local, state and national health departments. Identified papers (n = 1775) were screened and duplicates removed. Information was extracted and summarised from 116 papers that met review inclusion criteria (70 from electronic medical databases and 45 from the grey literature). This review identified that existing services struggle to meet demand. Barriers to effective child health service delivery in remote Australia include availability of trained staff, limited services, and difficult access. Aboriginal and Community Controlled Health Organisations are effective and should receive increased support including increased training and remuneration for Aboriginal Health Workers. Continuous quality assessment of existing and future programs will improve quality; as will measures that reflect aboriginal ways of knowing and being, that go beyond traditional Key Performance Indicators. Best practice models for service delivery have community leadership and collaboration. Increased resources with a focus on primary prevention and health promotion are essential.

Abstract
OBJECTIVES Ovarian cancer is the leading cause of death from gynaecological cancer in the UK, making early diagnosis key. The two-week wait pathway aims to facilitate rapid referrals from primary to secondary care for suspected cancer thus increasing rates of early diagnosis. The objective of this study was to evaluate referrals made via the two-week wait pathway for suspected ovarian cancer. STUDY DESIGN A retrospective analysis of 215 women referred on the two-week wait pathway to a tertiary centre in the United Kingdom with suspected ovarian cancer in 2018. RESULTS Only 16% of women referred were subsequently diagnosed with gynaecological malignancy. Of those diagnosed with ovarian cancer, 78% had late stage disease at diagnosis. Pre-menopausal women made up 29% of those referred, but only 6% of those diagnosed with cancer. CONCLUSION Despite its goal of increasing early stage diagnosis of cancer, the majority of women referred via the two-week wait pathway do not have cancer, and the majority of those who do are referred with late stage disease. These results highlight the need for an effective screening programme for ovarian cancer.

Abstract
Background. Aboriginal leaders invited us to examine the frequency and reasons for emergency department (ED) presentations by children in remote Western Australia, where Prenatal Alcohol Exposure (PAE) is common. Methods. ED presentations (2007-11 inclusive) were examined for all children born in the Fitzroy Valley in 2002-03. Results. ED data for 127/134 (94.7%) children (95% Aboriginal) showed 1058 presentations over 5-years. Most (81%) had at least 1 presentation (median 9.0, range 1-50). Common presentations included: screening/follow-up/social reasons (16.0%), injury (15.1%), diseases of the ear (14.9%), skin (13.8%), respiratory tract (13.4%), and infectious and parasitic diseases (9.8%). PAE and higher presentations rates were associated. Commonly associated socio-economic factors were household over-crowding, financial and food insecurity. Conclusion. Children in very remote Fitzroy Crossing communities have high rates of preventable ED presentations, especially those with PAE. Support for culturally appropriate preventative programs and improved access to primary health services need to be provided in remote Australia.

Abstract
The World Health Organization reported that half or more of all under five deaths were caused by undernutrition in developing countries, with the majority of these deaths occurring in the first week of life. Even if the undernourished neonates manage to survive, they are exposed to long-term health impacts, including obesity, cardiovascular disease, and hypertension. Along with those health-impacts they can be exposed to risks related to detrimental early development, such as physical impairment, stunting, brain dysfunction, and reduced cognitive development. Body fat percentage has been recognized to be closely associated with undernutrition in neonates. In this article, the potential of near infrared spectroscopy (NIRS), along with previous methods to measure body fat in neonates, is reviewed and discussed.

Abstract
Background With the greatest burden of infant undernutrition and morbidity in low and middle income countries (LMICs), there is a need for suitable approaches to monitor infants in a simple, low-cost and effective manner. Anthropometry continues to play a major role in characterising growth and nutritional status. Methods We developed a range of models to aid in identifying neonates at risk of malnutrition. We first adopted a logistic regression approach to screen for a composite neonatal morbidity, low and high body fat (BF%) infants. We then developed linear regression models for the estimation of neonatal fat mass as an assessment of body composition and nutritional status. Results We fitted logistic regression models combining up to four anthropometric variables to predict composite morbidity and low and high BF% neonates. The greatest area under receiver-operator characteristic curves (AUC with 95% confidence intervals (CI)) for identifying composite morbidity was 0.740 (0.63, 0.85), resulting from the combination of birthweight, length, chest and mid-thigh circumferences. The AUCs (95% CI) for identifying low and high BF% were 0.827 (0.78, 0.88) and 0.834 (0.79, 0.88), respectively. For identifying composite morbidity, BF% as measured via air displacement plethysmography showed strong predictive ability (AUC 0.786 (0.70, 0.88)), while birthweight percentiles had a lower AUC (0.695 (0.57, 0.82)). Birthweight percentiles could also identify low and high BF% neonates with AUCs of 0.792 (0.74, 0.85) and 0.834 (0.79, 0.88). We applied a sex-specific approach to anthropometric estimation of neonatal fat mass, demonstrating the influence of the testing sample size on the final model performance. Conclusions These models display potential for further development and evaluation in LMICs to detect infants in need of further nutritional management, especially where traditional methods of risk management such as birthweight for gestational age percentiles may be variable or non-existent, or unable to detect appropriately grown, low fat newborns.

Abstract
BACKGROUND We analysed hospital admissions of a predominantly Aboriginal cohort of children in the remote Fitzroy Valley in Western Australia during the first 7 years of life. METHODS All children born between January 1, 2002 and December 31, 2003 and living in the Fitzroy Valley in 2009-2010 were eligible to participate in the Lililwan Project. Of 134 eligible children, 127 (95%) completed Stage 1 (interviews of caregivers and medical record review) in 2011 and comprised our cohort. Lifetime (0-7 years) hospital admission data were available and included the dates, and reasons for admission, and comorbidities. Conditions were coded using ICD-10-AM discharge codes. RESULTS Of the 127 children, 95.3% were Indigenous and 52.8% male. There were 314 admissions for 424 conditions in 89 (70.0%) of 127 children. The 89 children admitted had a median of five admissions (range 1-12). Hospitalization rates were similar for both genders (p = 0.4). Of the admissions, 108 (38.6%) were for 56 infants aged <12 months (median = 2.5, range = 1-8). Twelve of these admissions were in neonates (aged 0-28 days). Primary reasons for admission (0-7 years) were infections of the lower respiratory tract (27.4%), gastrointestinal system (22.7%), and upper respiratory tract (11.4%), injury (7.0%), and failure to thrive (5.4%). Comorbidities, particularly upper respiratory tract infections (18.1%), failure to thrive (13.6%), and anaemia (12.7%), were common. In infancy, primary cause for admission were infections of the lower respiratory tract (40.8%), gastrointestinal (25.9%) and upper respiratory tract (9.3%). Comorbidities included upper respiratory tract infections (33.3%), failure to thrive (18.5%) and anaemia (18.5%). CONCLUSION In the Fitzroy Valley 70.0% of children were hospitalised at least once before age 7 years and over one third of admissions were in infants. Infections were the most common reason for admission in all age groups but comorbidities were common and may contribute to need for admission. Many hospitalizations were feasibly preventable. High admission rates reflect disadvantage, remote location and limited access to primary healthcare and outpatient services. Ongoing public health prevention initiatives including breast feeding, vaccination, healthy diet, hygiene and housing improvements are crucial, as is training of Aboriginal Health Workers to increase services in remote communities.

Abstract
BACKGROUND Sudden infant death syndrome (SIDS) has been most recently defined as the sudden unexpected death of an infant less than one year of age, with onset of the fatal episode apparently occurring during sleep, that remains unexplained after a thorough investigation, including the performance of a complete autopsy and a review of the circumstances of death and clinical history. Despite the success of several prevention campaigns, SIDS remains a leading cause of infant mortality. In 1994, a 'triple risk model' for SIDS was proposed that described SIDS as an event that results from the intersection of three factors: a vulnerable infant; a critical development period in homeostatic control (age related); and an exogenous stressor. The association between pacifier (dummy) use and reduced incidence of SIDS has been shown in epidemiological studies since the early 1990s. Pacifier use, given its low cost, might be a cost-effective intervention for SIDS prevention if it is confirmed effective in randomised controlled trials. OBJECTIVES To determine whether the use of pacifiers during sleep versus no pacifier during sleep reduces the risk of SIDS. SEARCH METHODS We used the standard search strategy of the Cochrane Neonatal Review Group to search the Cochrane Central Register of Controlled Trials (CENTRAL 2016, Issue 2), MEDLINE via PubMed, Embase, and CINAHL to 16 March 2016. We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. SELECTION CRITERIA Published and unpublished controlled trials using random and quasi-random allocations of infants born at term and at preterm (less than 37 weeks' gestation) or with low birth weight (< 2500 g). Infants must have been randomised by one month' postmenstrual age. We planned to include studies reported only by abstracts, and cluster and cross-over randomised trials. DATA COLLECTION AND ANALYSIS Two review authors independently reviewed studies from searches. We found no eligible studies. MAIN RESULTS We identified no randomised controlled trials examining infant pacifiers for reduction in risk of SIDS. AUTHORS' CONCLUSIONS We found no randomised control trial evidence on which to support or refute the use of pacifiers for the prevention of SIDS.

Abstract
BACKGROUND The incidence of sudden unexpected early neonatal death (SUEND) or acute life-threatening events (ALTEs) is reported as 0.05/1,000 to 0.38/1,000 live births. There is currently no national system in Australia for reporting and investigating such cases. METHODS A 3-y prospective, national surveillance study, run in collaboration with the Australian Pediatric Surveillance Unit (APSU). Data were provided by pediatricians reporting to APSU; and independently ascertained by the Coroner in two states (NSW and QLD) and the Newborn Early Transport Network in NSW. A detailed deidentified questionnaire was created. RESULTS In NSW and QLD, the incidence was 0.1 and 0.08/1,000 live births, respectively. Forty-eight definitive cases were identified. Common causes included accidental asphyxia, cardiac disease, persistent pulmonary hypertension of the newborn, and sudden infant death syndrome. Twenty-six babies collapsed on day 1 and 19 were found on the carer's chest. CONCLUSION The incidence in NSW and QLD is higher than previously published. The first postnatal day is a vulnerable period for newborns, who require close observation particularly during skin-to-skin contact. Development and implementation of guidelines for safe sleeping in hospital are needed. Collaboration between obstetricians, midwives, and pediatricians is essential to ensure safety of the newborn.

Abstract
OBJECTIVE Pregnancies complicated with gestational diabetes mellitus (GDM) are at a higher risk for caesarean and instrumental deliveries as well as adverse neonatal outcomes such as fetal overgrowth, hypoglycaemia and neonatal intensive care admission. Our primary objective was to describe neonatal outcomes in a sample that included term infants of both GDM mothers and mothers with normal glucose tolerance (NGT). DESIGN AND SETTING this cross-sectional study included 599 term babies born between September and October 2010 at Royal Prince Alfred Hospital, Sydney, Australia. Maternal and neonatal data were collected from medical records and a questionnaire. Glycaemic control data was based on third trimester HbA1c levels and self-monitoring blood glucose levels (BGL). Univariate associations between GDM status and maternal demographic factors, as well as pregnancy outcomes, were estimated using χ(2) tests and t-tests, as appropriate. FINDINGS of 599 babies, 67(11%) were born to GDM mothers. GDM mothers were more likely to be overweight/obese and of Asian ethnicity. Good glycaemic control was achieved in most GDM mothers. GDM babies were more likely to have been induced (p=0.013) and delivered earlier than non-GDM mothers (p<0.001), and they were also more likely to be breastfed within one hour of birth. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE in this study, GDM infants were more likely to be induced and delivered earlier but otherwise they did not have significantly different neonatal outcomes compared to infants of NGT mothers. This can be attributed to the good GDM control by lifestyle modification and insulin if necessary. The role of labour induction in GDM pregnancies should be further investigated. Midwives have an important role in maternal education during pregnancy and in the postnatal period.

Abstract
Background The Northern Territory has the highest rates of perinatal morbidity and mortality in Australia. Placental histopathology has not been studied in this high-risk group of women. Methods This is the first study to detail the placental pathology in Indigenous women and to compare the findings with non-Indigenous women in the Northern Territory. There were a total of 269 deliveries during a three-month period from the 27th of June to the 27th of August 2009. Seventy-one (71%) percent of all placentas were examined macroscopically, sectioned then reviewed by a Perinatal Pathologist, blinded to the maternal history and outcomes. Results Indigenous women were found to have higher rates of histologically confirmed chorioamnionitis and or a fetal inflammatory response compared with non-Indigenous women (46% versus 26%; OR 2.4, 95% CI 1.3-4.5). In contrast, non-Indigenous women were twice as likely to show vascular related pathology (31% versus 14%; OR 2.77, 95% CI 1.3-5.9). Indigenous women had significantly higher rates of potentially modifiable risk factors for placental inflammation including genitourinary infections, anaemia and smoking. After adjusting for confounders, histological chorioamnionitis and fetal inflammatory response was significantly associated with rural or remote residence (Adjusted OR 2.5, 95% CI 1.08 – 5.8). Conclusion This study has revealed a complex aetiology underlying a high prevalence of placental inflammation in the Northern Territory. Placental inflammation is associated with rural and remote residence, which may represent greater impact of systemic disadvantage, particularly affecting Indigenous women in the Northern Territory.

Abstract
BACKGROUND Gastro-oesophageal reflux (GOR) is commonly diagnosed in the neonatal population (DiPietro 1994), and generally causes few or no symptoms (Vandenplas 2009). Conversely, gastro-oesophageal reflux disease (GORD) refers to GOR that causes troublesome symptoms with or without complications such as damage to the oesophagus (Vandenplas 2009). Currently there is no evidence to support the range of measures recommended to help alleviate acid reflux experienced by infants. Non-nutritive sucking (NNS) has been used as an intervention to modulate neonatal state behaviours through its pacifying effects such as decrease infant fussiness and crying during feeds (Boiron 2007; Pickler 2004). OBJECTIVES To determine if NNS reduces GORD in preterm infants (less than 37 weeks' gestation) and low birth weight (less than 2500 g) infants, three months of age and less, with signs or symptoms suggestive of GORD, or infants with a diagnosis of GORD. SEARCH METHODS We performed computerised searches of the electronic databases of the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 9, 2013), MEDLINE (1966 to September 2013), CINAHL (1982 to September 2013), and EMBASE (1988 to September 2013). We applied no language restrictions. SELECTION CRITERIA Controlled trials using random or quasi-random allocation of preterm infants (less than 37 weeks' gestation) and low birth weight (less than 2500 g) infants three months of age and less with signs or symptoms suggestive of GORD, or infants with a diagnosis of GORD. We included studies reported only by abstracts, and cluster and cross-over randomised trials. DATA COLLECTION AND ANALYSIS Two review authors independently reviewed and selected trials from searches, assessed and rated study quality and extracted relevant data. We identified two studies from the initial search. After further review, we excluded both studies. MAIN RESULTS We identified no studies examining the effects of NNS for GORD in preterm and low birth weight infants AUTHORS' CONCLUSIONS There was insufficient evidence to determine the effectiveness of NNS for GORD. Adequately powered RCTs on the effect of NNS in preterm and low birth weight infants diagnosed with GORD are required.

Abstract
OBJECTIVE To compare body composition of large-for-gestational-age (LGA) with appropriate-for-gestational-age (AGA) newborns and to identify antenatal predictors of LGA. STUDY DESIGN This cross-sectional study included 536 term, singleton infants. Anthropometric measurements were performed within 48 h of birth and included determination of body fat percentage (%BF) by air displacement plethysmography. Associations were investigated using logistic regression. RESULT LGA infants had greater %BF (P<0.001) compared with AGA infants. Significant predictors of LGA infants included parity (odds ratio (OR)=1.98, (95% confidence interval (CI) 1.00, 4.02)), paternal height (OR=1.08, (95% CI 1.03, 1.14)), maternal pregravid weight (65 to 74.9 kg: OR=2.77, (95% CI 1.14, 7.06)) and gestational weight gain (OR=1.09, 95% CI (1.03, 1.16)). Gestational diabetes mellitus was not associated with LGA infants (P=0.598). CONCLUSION Paternal height, parity, maternal pregravid weight and gestational weight gain were strongly associated with LGA infants. These results may allow early prediction and potential modification, thereby optimising clinical outcomes.

Abstract
BACKGROUND Fetal growth restriction is defined as failure to reach growth potential and considered one of the major complications of pregnancy. These infants are often, although not universally, small for gestational age (SGA). SGA is defined as a weight less than a specified percentile (usually the 10th percentile). Identification of SGA infants is important because these infants are at increased risk of perinatal morbidity and mortality. Screening for SGA is a challenge for all maternity care providers and current methods of clinical assessment fail to detect many infants who are SGA. Large observational studies suggest that customised growth charts may be better able to differentiate between constitutional and pathologic smallness. Customised charts adjust for physiological variables such as maternal weight and height, ethnicity and parity. OBJECTIVES To assess the benefits and harms of using population-based growth charts compared with customised growth charts as a screening tool for detection of fetal growth in pregnant women. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (12 March 2014), reviewed published guidelines and searched the reference lists of review articles. SELECTION CRITERIA Randomised, quasi-randomised or cluster-randomised clinical trials comparing customised versus population-based growth charts used as a screening tool for detection of fetal growth in pregnant women. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion. MAIN RESULTS No randomised trials met the inclusion criteria. AUTHORS' CONCLUSIONS There is no randomised trial evidence currently available. Further randomised trials are required to accurately assess whether the improvement in detection shown is secondary to customised charts alone or an effect of the policy change. Future research in large trials is needed to investigate the benefits and harms (including perinatal mortality) of using customised growth charts in different settings and for both fundal height and ultrasound measurements.

Abstract
BACKGROUND Undernutrition in neonates increases the risk of serious morbidities. The objective of this study was to describe neonatal morbidity associated with low body fat percentage (BF%) and measure the number of undernourished neonates defined by BF% and compare this with birth weight percentiles (<10th). METHODS Eligibility included term (≥37 wk) neonates. BF% measurements were undertaken by air displacement plethysmography. Data on neonatal outcomes were extracted from medical records and used to develop a measure of neonatal morbidity. We assessed the association between neonatal morbidity and population-based birth weight percentiles compared with the BF% measurements. RESULTS Five hundred and eighty-one neonates were included. Low BF% was defined by 1 SD below the mean and identified in 73 per 1,000 live births. Neonatal morbidity was found in 3.4% of neonates. Birth weight percentile was associated with neonatal morbidity (odds ratio (OR): 1.03 (95% confidence interval (CI): 1.01, 1.05); P = <0.001). BF% was associated with a higher risk of neonatal morbidity (OR: 1.30 (95% CI: 1.15, 1.47); P = <0.001). CONCLUSION In this population, measuring BF% is more closely associated with identification of neonates at risk of neonatal morbidity as compared with birth weight percentiles. BF% measurements could assist with identifying neonates who are appropriately grown yet undernourished and exclude small neonates not at risk.

Abstract
Customized birth weight charts that incorporate maternal characteristics are now being adopted into clinical practice. However, there is controversy surrounding the value of these charts in the prediction of growth and perinatal outcomes. The objective of this study was to assess the use of customized charts in predicting growth, defined by body fat percentage, and perinatal morbidity. A total of 581 term (≥37 weeks' gestation) neonates born in Sydney, Australia, in 2010 were included. Body fat percentage measurements were taken by using air displacement plethysmography. Objective composite measurements of perinatal morbidity were used to identify neonates who had poor outcomes; these data were extracted from medical records. The value of customized charts was assessed by calculating positive predictive values, negative predictive values, and odds ratios with 95% confidence intervals. Customized versus population-based charts did not improve the prediction of either low body fat percentage (59% vs. 66% positive predictive value and 87% vs. 89% negative predictive value, respectively) or high body fat percentage (48% vs. 53% positive predictive value and 90% vs. 89% negative predictive value, respectively). Customized charts were not better than population-based charts at predicting perinatal morbidity (for customized charts, odds ratio = 1.02, 95% confidence interval: 1.01, 1.04; for population-based charts, odds ratio = 1.03, 95% confidence interval: 1.01, 1.05) per percentile decrease in birth weight. Customized birth weight charts do not provide significant improvements over population-based charts in predicting neonatal growth and morbidity.

Abstract
AIM This study aims to evaluate adherence to a clinical guideline for screening and prevention of neonatal hypoglycaemia on the post-natal wards. METHODS Retrospective chart review of 581 healthy term neonates born at a tertiary maternity hospital. Indications for hypoglycaemia screening included small for gestational age (SGA), infants of diabetic mothers (IDM; gestational, Type 1 or 2), symptomatic hypoglycaemia, macrosomia and wasted (undernourished) appearance. Outcomes were protocol entry and adherence with hypoglycaemia prevention strategies including early and frequent feeding and timely blood glucose measurement. RESULTS Of 115 neonates screened for hypoglycaemia, 67 were IDM, 19 were SGA (including two both IDM and SGA), and two were macrosomic. One IDM and one SGA were not screened. Twenty-two neonates were screened for a reason not identifiable from the medical record, and 13 neonates were SGA by a definition different to the guideline definition, including five who were also IDM. Guideline adherence was variable. Few neonates (41 of 106, 39%) were fed in the first post-natal hour, and blood glucose measurement occurred later than recommended for 41 of 106 (39%) of neonates. CONCLUSIONS Most IDM and SGA neonates were screened. While guideline adherence overall was comparable with other studies, neonates were fed late. We recommend staff education about benefits of early (within the first hour) frequent breastfeeding for neonates at risk.

Abstract
OBJECTIVE We aimed to compare the discriminative power of prognostic models for early prediction of women at risk for the development of gestational diabetes mellitus (GDM) using four currently recommended diagnostic criteria based on the 75-g oral glucose tolerance test (OGTT). We also described the potential effect of application of the models into clinical practice. RESEARCH DESIGN AND METHODS A prospective cross-sectional study of 2,772 pregnant women was conducted at a referral maternity center in Vietnam. GDM was determined by the American Diabetes Association (ADA), International Association of the Diabetes and Pregnancy Study Groups (IADPSG), Australasian Diabetes in Pregnancy Society (ADIPS), and World Health Organization (WHO) criteria. Prognostic models were developed using the Bayesian model averaging approach, and discriminative power was assessed by area under the curve. Different thresholds of predicted risk of developing GDM were applied to describe the clinical impact of the diagnostic criteria. RESULTS The magnitude of GDM varied substantially by the diagnostic criteria: 5.9% (ADA), 20.4% (IADPSG), 20.8% (ADIPS), and 24.3% (WHO). The ADA prognostic model, consisting of age and BMI at booking, had the best discriminative power (area under the curve of 0.71) and the most favorable cost-effective ratio if implemented in clinical practice. Selective screening of women for GDM using the ADA model with a risk threshold of 3% gave 93% sensitivity for identification of women with GDM with a 27% reduction in the number of OGTTs required. CONCLUSIONS A simple prognostic model using age and BMI at booking could be used for selective screening of GDM in Vietnam and in other low- and middle-income settings.

Abstract
AIM The study aims to assess accuracy of standard practice measurement of neonatal length compared with a gold-standard length-board technique. METHODS Data were obtained from a population-based, cross-sectional study of 602 term babies at Royal Prince Alfred Hospital, Sydney, Australia, in 2010. Neonatal length was measured by standard clinical practice and by a length-board (gold standard) and measurements compared. Standard growth curve percentiles were used to plot length measurements. The Bland and Altman method was used to assess agreement, and acceptable levels of agreement were set at ≤1 cm and ≤0.5 cm. RESULTS The limits of agreement were between -3.06 cm (95% CI -3.08 to -3.04) and 2.67 cm (95% CI 2.65 to 2.69). Neonates whose standard-practice length fell within 0.5 cm of the gold standard totalled 41% (241 neonates), while 59% (342) were >0.5 cm. The change in length resulted in a change in the percentile range of 53% (309) on a standard growth curve percentile. When examining neonates whose length was plotted at the extremes of percentile regions, the positive predictive value results of the standard practice compared with the gold standard were poor, with positive predictive values of 37.5%, 57.1% and 31.3% for neonates who were measured as <3rd, <10th and ≥90th percentile, respectively. CONCLUSIONS In current clinical practice, measures of neonatal length are often inaccurate, which has implications for potentially erroneous clinical care. Health-care providers should be educated on the importance of length and trained in how to measure length with the correct technique using a length-board.

Abstract
OBJECTIVE This study aims to describe body composition in term infants of mothers with gestational diabetes mellitus (GDM) compared with infants of mothers with normal glucose tolerance (NGT). RESEARCH DESIGN AND METHODS This cross-sectional study included 599 term babies born at Royal Prince Alfred Hospital, Sydney, Australia. Neonatal body fat percentage (BF%) was measured within 48 h of birth using air-displacement plethysmography. Glycemic control data were based on third-trimester HbA(1c) levels and self-monitoring blood glucose levels. Associations between GDM status and BF% were investigated using linear regression adjusted for relevant maternal and neonatal variables. RESULTS Of 599 babies, 67 (11%) were born to mothers with GDM. Mean ± SD neonatal BF% was 7.9 ± 4.5% in infants with GDM and 9.3 ± 4.3% in infants with NGT, and this difference was not statistically significant after adjustment. Good glycemic control was achieved in 90% of mothers with GDM. CONCLUSIONS In this study, neonatal BF% did not differ by maternal GDM status, and this may be attributed to good maternal glycemic control.

Abstract
BACKGROUND Although systematic use of the Perinatal Society of Australia and New Zealand internationally endorsed Clinical Practice Guideline for Perinatal Mortality (PSANZ-CPG) improves health outcomes, implementation is inadequate. Its complexity is a feature known to be associated with non-compliance. Interactive education is effective as a guideline implementation strategy, but lacks an agreed definition. SCORPIO is an educational framework containing interactive and didactic teaching, but has not previously been used to implement guidelines. Our aim was to transform the PSANZ-CPG into an education workshop to develop quality standardised interactive education acceptable to participants for learning skills in collaborative interprofessional care. METHODS The workshop was developed using the construct of an educational framework (SCORPIO), the PSANZ-CPG, a transformation process and tutor training. After a pilot workshop with key target and stakeholder groups, modifications were made to this and subsequent workshops based on multisource written observations from interprofessional participants, tutors and an independent educator. This participatory action research process was used to monitor acceptability and educational standards. Standardised interactive education was defined as the attainment of content and teaching standards. Quantitative analysis of positive expressed as a percentage of total feedback was used to derive a total quality score. RESULTS Eight workshops were held with 181 participants and 15 different tutors. Five versions resulted from the action research methodology. Thematic analysis of multisource observations identified eight recurring education themes or quality domains used for standardisation. The two content domains were curriculum and alignment with the guideline and the six teaching domains; overload, timing, didacticism, relevance, reproducibility and participant engagement. Engagement was the most challenging theme to resolve. Tutors identified all themes for revision whilst participants identified a number of teaching but no content themes. From version 1 to 5, a significant increasing trend in total quality score was obtained; participants: 55%, p=0.0001; educator: 42%, p=0.0004; tutor peers: 57%, p=0.0001. CONCLUSIONS Complex clinical guidelines can be developed into a workshop acceptable to interprofessional participants. Eight quality domains provide a framework to standardise interactive teaching for complex clinical guidelines. Tutor peer review is important for content validity. This methodology may be useful for other guideline implementation.

Abstract
Background Diabetes is increasing in prevalence globally, notably amongst populations from low- and middle- income countries. Gestational Diabetes Mellitus(GDM), a precursor for type 2 diabetes, is increasing in line with this trend. Few studies have considered the personal and social effects of GDM on women living in low and middle-income countries. The aim of this study was determine attitudes and health behaviours of pregnant women with GDM in Vietnam. Methods This was a qualitative study using focus group methodology conducted in Ho Chi Minh City. Pregnant women, aged over 18 years, with GDM were eligible to participate. Women were purposely sampled to obtain a range of gestational ages and severity of disease. They were invited to attend a 1-hour focus group. Questions were semi structured around six themes. Focus groups were recorded, transcribed, translated and cross-referenced. Non-verbal and group interactions were recorded. Thematic analysis was performed using a theoretical framework approach. Results From December 2010 to February 2011, four focus groups were conducted involving 34 women. Median age was 31.5 years (range 23 to 44), median BMI 21.8 kg/m2. Women felt confusion, anxiety and guilt about GDM. Many perceived their baby to be at increased risk of death. Advice to reduce dietary starch was confusing. Women reported being ‘hungry’ or ‘starving’ most of the time, unaware of appropriate food substitutions. They were concerned about transmission of GDM through breast milk. Several women planned not to breastfeed. All felt they needed more information. Current sources of information included friends, magazines, a health phone line or the Internet. Women felt small group sessions and information leaflets could benefit them. Conclusions This study highlights the need for culturally appropriate clinical education and health promotion activities for women with GDM in Vietnam.

Abstract
BACKGROUND Fetal growth restriction is defined as failure to reach growth potential and considered one of the major complications of pregnancy. These infants are often, although not universally, small for gestational age (SGA). SGA is defined as a weight less than a specified percentile (usually the 10th percentile). Identification of SGA infants is important because these infants are at increased risk of perinatal morbidity and mortality. Screening for SGA is a challenge for all maternity care providers and current methods of clinical assessment fail to detect many infants that are SGA. Large observational studies suggest that customised growth charts may be better able to differentiate between constitutional and pathologic smallness. Customised charts adjust for physiological variables such as maternal weight and height, ethnicity and parity. OBJECTIVES To assess the benefits and harms of using population-based growth charts compared with customised growth charts as a screening tool for detection of fetal growth in pregnant women. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 September 2011), reviewed published guidelines and searched the reference lists of review articles. SELECTION CRITERIA Randomised, quasi-randomised or cluster randomised clinical trials comparing customised versus population-based growth charts used as a screening tool for detection of fetal growth in pregnant women. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion. MAIN RESULTS No randomised trials met the inclusion criteria. AUTHORS' CONCLUSIONS There is no randomised trial evidence currently available. Further randomised trials are required to accurately assess whether the improvement in detection shown is secondary to customised charts alone or an effect of the policy change. Future research in large trials is needed to investigate the benefits and harms (including perinatal mortality) of using customised growth charts in different settings and for both fundal height and ultrasound measurements.

Abstract
BACKGROUND Over 2.6 million babies are stillborn every year mostly in low- and middle-income countries, where cause of death remains often unexplained. AIM To determine the applicability and utility of the Perinatal Society of Australia and New Zealand (PSANZ) Clinical Practice Guideline (CPG) for Perinatal Mortality in reducing the proportion of unexplained stillbirths in a hospital setting in Vietnam. METHODS An analytic cross-sectional study of stillborn babies born at a major maternity facility in Vietnam. Maternal history, external physical examination of the baby and placental macroscopic examination were performed. Two experienced classifiers independently assigned PSANZ perinatal death classification (PDC). This was compared to cause of death documented in the hospital records. RESULTS 107 stillborn babies were born to 105 mothers. The proportion of stillborn babies classified as unexplained was reduced from 52.3 to 24.3% (P < 0.01) using the PSANZ-PDC system. Causes of death were congenital abnormalities (35.6%), hypertension (8.4%), fetal growth restriction (8.4%), specific perinatal conditions (8.4%), spontaneous preterm (6.5%), maternal conditions (5.6%) and antepartum haemorrhage (3.7%). CONCLUSIONS Application of the PSANZ-CPG and stillbirth classification system is effective and feasible in a low-income country facility setting and resulted in a reduction in the number of babies classified as unexplained stillbirth in Vietnam.

Abstract
OBJECTIVE To describe major epidemiologic and placental findings regarding stillbirth in Vietnam. METHODS A cross-sectional study of all stillbirths in a tertiary referral facility in Ho Chi Minh City, Vietnam, was performed. Detailed examination of each infant, placental pathology, and semi-structured maternal interviews were conducted according to the Perinatal Society of Australia and New Zealand Perinatal Death Classification guidelines. Maternal, fetal, and placental characteristics were examined. RESULTS Between December 8, 2008, and January 9, 2009, there were 4694 live births and 122 stillbirths at the facility. In total, 107 (87.7%) cases were included in the study. Low education level was associated with a lack of prenatal care; induced abortion accounted for 34.6% of fetal deaths (gender selection was not the reason); 35.5% of infants were born at 22-28 weeks of gestation; 31.8% of stillbirths were small for gestational age; histologic evidence of chorioamnionitis was present in 40.2% of cases. Calcium supplements were less likely to have been taken in cases in which death from hypertension occurred. alpha-Thalassemia was the main cause of fetal hydrops (6.2%). CONCLUSION Improving access to prenatal care and prenatal calcium and iron supplementation, and screening for congenital abnormalities and alpha-thalassemia may help to reduce rates of perinatal death in Vietnam.

Abstract
BACKGROUND Neonatal abstinence syndrome (NAS) due to opiate withdrawal may result in disruption of the mother-infant relationship, sleep-wake abnormalities, feeding difficulties, weight loss and seizures. OBJECTIVES To assess the effectiveness and safety of using an opiate compared to a sedative or non-pharmacological treatment for treatment of NAS due to withdrawal from opiates. SEARCH STRATEGY The review was updated in 2010 with additional searches CENTRAL, MEDLINE and EMBASE supplemented by searches of conference abstracts and citation lists of published articles. SELECTION CRITERIA Randomized or quasi-randomized controlled trials of opiate treatment in infants with NAS born to mothers with opiate dependence. DATA COLLECTION AND ANALYSIS Each author assessed study quality and extracted data independently. MAIN RESULTS Nine studies enrolling 645 infants met inclusion criteria. There were substantial methodological concerns in all studies comparing an opiate with a sedative. Two small studies comparing different opiates were of good methodology.Opiate (morphine) versus supportive care (one study): A reduction in time to regain birth weight and duration of supportive care and a significant increase in hospital stay was noted.Opiate versus phenobarbitone (four studies): Meta-analysis found no significant difference in treatment failure. One study reported opiate treatment resulted in a significant reduction in treatment failure in infants of mothers using only opiates. One study reported a significant reduction in days treatment and admission to the nursery for infants receiving morphine. One study reported a reduction in seizures, of borderline statistical significance, with the use of opiate.Opiate versus diazepam (two studies): Meta-analysis found a significant reduction in treatment failure with the use of opiate.Different opiates (six studies): there is insufficient data to determine safety or efficacy of any specific opiate compared to another opiate. AUTHORS' CONCLUSIONS Opiates compared to supportive care may reduce time to regain birth weight and duration of supportive care but increase duration of hospital stay. When compared to phenobarbitone, opiates may reduce the incidence of seizures but there is no evidence of effect on treatment failure. One study reported a reduction in duration of treatment and nursery admission for infants on morphine. Compared to diazepam, opiates reduce the incidence of treatment failure. A post-hoc analysis generates the hypothesis that initial opiate treatment may be restricted to infants of mothers who used opiates only. In view of the methodologic limitations of the included studies the conclusions of this review should be treated with caution.

Abstract
BACKGROUND Neonatal abstinence syndrome (NAS) due to opiate withdrawal may result in disruption of the mother-infant relationship, sleep-wake abnormalities, feeding difficulties, weight loss and seizures. Treatments used to ameliorate symptoms and reduce morbidity include opiates, sedatives and non-pharmacological treatments. OBJECTIVES To assess the effectiveness and safety of using a sedative compared to a non-opiate control for NAS due to withdrawal from opiates, and to determine which type of sedative is most effective and safe. SEARCH STRATEGY This update included searches of the Cochrane Central Register of Controlled Trials (Issue 1, 2010), MEDLINE 1966 to April 2010 and abstracts of conference proceedings. SELECTION CRITERIA Trials enrolling infants with NAS born to mothers with an opiate dependence with > 80% follow-up and using random or quasi-random allocation to sedative or control. Control could include another sedative or non-pharmacological treatment. DATA COLLECTION AND ANALYSIS Each author assessed study quality and extracted data independently. MAIN RESULTS Seven studies enrolling 385 patients were included. There were substantial methodological concerns for most studies including the use of quasi-random allocation methods and sizeable, largely unexplained differences in reported numbers allocated to each group.One study reported phenobarbitone compared to supportive care alone did not reduce treatment failure or time to regain birthweight, but resulted in a significant reduction in duration of supportive care (MD -162.1 min/day, 95% CI -249.2, -75.1). Comparing phenobarbitone to diazepam, meta-analysis of two studies found phenobarbitone resulted in a significant reduction in treatment failure (typical RR 0.39, 95% CI 0.24, 0.62). Comparing phenobarbitone with chlorpromazine, one study reported no significant difference in treatment failure.In infants treated with an opiate, one study reported addition of clonidine resulted in no significant difference in treatment failure, seizures or mortality. In infants treated with an opiate, one study reported addition of phenobarbitone significantly reduced the proportion of time infants had a high abstinence severity score, duration of hospitalisation and maximal daily dose of opiate. AUTHORS' CONCLUSIONS Infants with NAS due to opiate withdrawal should receive initial treatment with an opiate. Where a sedative is used, phenobarbitone should be used in preference to diazepam. In infants treated with an opiate, the addition of phenobarbitone or clonidine may reduce withdrawal severity. Further studies are needed to determine the role of sedatives in infants with NAS due to opiate withdrawal and the safety and efficacy of adding phenobarbitone or clonidine in infants treated with an opiate for NAS.

Abstract
UNLABELLED OBJECTIVE To determine the impact of intrauterine inflammation of maternal (chorioamnionitis) and fetal (umbilical vasculitis) origin and neonatal sepsis on the development of neonatal chronic lung disease in preterm infants. METHODS This study was conducted at Royal Prince Alfred Hospital in Sydney, Australia. All infants born at <30 weeks' gestation, admitted to the NICU, and surviving to 36 weeks' corrected gestation during 1992-2004 were eligible. Infants with major congenital abnormalities and those without placental examination were excluded. Antenatal and perinatal data extracted from hospital databases were correlated with the independent, central neonatal database and diagnostic laboratory reports. Neonatal sepsis was categorized according to blood culture isolates into 3 groups: coagulase-negative staphylococci, other bacteria, and Candida species. RESULTS There were 798 eligible infants born during the study period, and 761 (95.4%) had placental examination. The mean gestational age was 27.4 +/- 1.5 weeks. Antenatal maternal steroids were given to 94.4%. Regression analysis showed that chorioamnionitis with umbilical vasculitis and increasing gestation were associated with reduced odds of chronic lung disease. Chorioamnionitis without umbilical vasculitis showed a trend to reduced odds of chronic lung disease. Birth weight at <3rd percentile and neonatal sepsis were associated with increased odds of chronic lung disease. CONCLUSIONS A fetal inflammatory response is protective for chronic lung disease. Neonatal sepsis is strongly associated with chronic lung disease, and the infecting organism is important. Coagulase-negative staphylococcal infection confers a risk for chronic lung disease similar to that of other bacteremias. Candidemia confers the greatest risk of chronic lung disease.

Abstract
OBJECTIVES To determine the impact of maternal and fetal intrauterine inflammatory responses (chorioamnionitis and umbilical vasculitis) on the development of neonatal respiratory distress syndrome (RDS) in preterm infants. DESIGN, SETTING AND SUBJECTS The study included all infants <30 weeks' gestation born at the Royal Prince Alfred Hospital, Sydney, Australia, and admitted to neonatal intensive care from 1992 to 2001. Those without placental examination were excluded. Antenatal and perinatal data were extracted from prospectively kept hospital databases and correlated with the independent, central neonatal database. Placentae were examined prospectively using a standardised, semi-quantitative method. MAIN OUTCOME MEASURE A diagnosis of neonatal RDS. RESULTS There were 766 eligible babies and 724 (94.5%) had placental examination. The mean (SD) gestational age of the cohort was 27.1 (1.6) weeks. Antenatal maternal steroids were given to 93.6%. Histological chorioamnionitis alone was evident in 19.1% of infants, and chorioamnionitis with umbilical vasculitis in 30.2%. Regression analysis showed that increasing gestational age (adjusted odds ratio (OR) 0.72, 95% CI 0.64 to 0.81), chorioamnionitis (adjusted OR 0.49, 95% CI 0.31 to 0.78), and chorioamnionitis with umbilical vasculitis (adjusted OR 0.23, 95% CI 0.15 to 0.35) were associated with a significant reduction in RDS. Factors associated with increased odds of RDS were multiple gestation (twin or triplet pregnancies), pregnancy-induced hypertension and an Apgar score <4 at 1 minute. CONCLUSIONS Maternal and fetal intrauterine inflammatory responses are both protective for RDS. The presence of chorioamnionitis with umbilical vasculitis is associated with a markedly greater reduction of RDS than chorioamnionitis alone.

Abstract
In Australia, as in other developed countries, approximately 40-50% of stillbirths are of unknown aetiology. Emerging evidence suggests stillbirths are often multifactorial. The absence of a known cause leads to uncertainty regarding the risk of recurrence, which can cause extreme anguish for parents that may manifest as guilt, anger or bewilderment. Further, clinical endeavours to prevent recurrences in future pregnancies are impaired by lack of a defined aetiology. Therefore, efforts to provide an aetiological diagnosis of stillbirth impact upon all aspects of care of the mother, and inform many parts of clinical decision making. Despite the magnitude of the problem, that is 7 stillbirths per 1000 births in Australia, diagnostic efforts to discover viral aetiologies are often minimal. Viruses and other difficult to culture organisms have been postulated as the aetiology of a number of obstetric and paediatric conditions of unknown cause, including stillbirth. Reasons forwarded for testing stillbirth cases for infectious agents are non-medical factors, including addressing all parents' need for diagnostic closure, identifying infectious agents as a sporadic cause of stillbirth to reassure parents and clinicians regarding risk for future pregnancies, and to reduce unnecessary testing. It is clear that viral agents including rubella, human cytomegalovirus (CMV), parvovirus B19, herpes simplex virus (HSV), lymphocytic choriomeningitis virus (LCMV), and varicella zoster virus (VZV) may cause intrauterine deaths. Evidence for many other agents is that minimal or asymptomatic infections also occur, so improved markers of adverse outcomes are needed. The role of other viruses and difficult-to-culture organisms in stillbirth is uncertain, and needs more research. However, testing stillborn babies for some viral agents remains a useful adjunct to histopathological and other examinations at autopsy. Modern molecular techniques such as multiplex PCR, allow searches for multiple agents. Now that such testing is available, it is important to assess the clinical usefulness of such testing.

Abstract
UNLABELLED In-utero drug exposure is associated with increased risks of perinatal morbidity and mortality, however longer term neurodevelopmental outcome of survivors is poorly described. AIMS The aims of this paper are: (1) to review the published literature which examines neurodevelopmental outcome in infants with Neonatal Abstinence Syndrome (NAS) and (2) to report developmental follow-up data from a case-control study of babies exposed to opiate in-utero. METHODS This study was conducted at Royal Prince Alfred Hospital in Sydney, NSW, through the multidisciplinary NAS service. Literature was reviewed after searching MEDLINE for relevant studies. Our own case-control study was conducted to examine neurodevelopmental outcome. A number of standardized neuropsychological tools were employed to assess these infants. RESULTS Results from previously published studies on outcome of infants with NAS were not reassuring as to reported 'normal development'. In our own case-control study, opiate-exposed infants were significantly more likely to have neurodevelopmental impairment compared to healthy control infants, when assessed at 18 months and 3 years of age. CONCLUSIONS Infants exposed to opiates in-utero are at increased risk of neurodevelopmental problems throughout early childhood.

Abstract
OBJECTIVE The purpose of this study was to determine the incidence of chorioamnionitis and fetal inflammatory response in a stillborn cohort and the relationship of fetal response to spontaneous labor, unexplained antepartum death, and spontaneous preterm death. STUDY DESIGN In a 15-year hospital cohort study, placental histopathologic evidence, labor onset, gestation, and cause of death classification data were analyzed. RESULTS Of 459 stillbirths, 428 stillbirths were included. The incidence of chorioamnionitis was 36.9%, with higher rates evident in early and late gestation. A fetal inflammatory response was present in 13.3% and correlated with spontaneous labor and very early spontaneous preterm death. The absence of a fetal response was associated with unexplained antepartum death. CONCLUSION The increased incidence of chorioamnionitis at extremes of gestation in stillbirth is novel and has important implications. The impact of a fetal response is gestation dependent and its absence is associated with unexplained antepartum death.

Abstract
BACKGROUND Late onset neonatal sepsis (systemic infection after 48 hours of age) continues to be a significant cause of morbidity and mortality. Early treatment with antibiotics is essential as infants can deteriorate rapidly. It is not clear which antibiotic regimen is most suitable for initial treatment of suspected late onset sepsis. OBJECTIVES To compare the effectiveness and adverse effects of different antibiotic regimens for treatment of suspected late onset sepsis in newborn infants. SEARCH STRATEGY The standard search strategy of the Cochrane Neonatal Review Group was used. This includes electronic searches of the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 4, 2004), MEDLINE (1966 - Dec 2004), EMBASE (1980 - Dec 2004) and CINAHL (1982 - Dec 2004), electronic abstracts of Pediatric Academic Society meetings (1996 - Dec 2004) and previous reviews including cross references (all articles referenced). SELECTION CRITERIA Randomised and quasi randomised controlled trials comparing different initial antibiotic regimens in neonates with suspected late onset sepsis were evaluated. DATA COLLECTION AND ANALYSIS Both reviewer authors screened abstracts and papers against the inclusion criteria, appraised the quality of and extracted data from papers. For dichotomous outcomes, treatment effect was expressed as relative risk and risk difference with 95% confidence intervals. NNT was calculated for outcomes for which there was a statistically significant reduction in risk difference. MAIN RESULTS Thirteen studies were identified as possibly eligible for inclusion. The majority of studies were excluded as they did not separate data for early and late onset infection. Two studies are still awaiting assessment. Only one small study, in 24 neonates, was included in this review. It compared beta-lactam therapy with a combination of beta lactam plus aminoglycoside. The study did not meet our prespecified criteria for good methodological quality. In babies with suspected infection there was no significant difference in mortality (RR 0.17, 95% CI 0.01 to 3.23) or treatment failure (RR 0.17, 95% CI 0.01 to 3.23). Antibiotic resistance was assessed and there were no cases in either group. AUTHORS' CONCLUSIONS There is inadequate evidence from randomised trials in favour of any particular antibiotic regimen for the treatment of suspected late onset neonatal sepsis. The available evidence is not of high quality. Although suspected sepsis and antibiotic use is common, quality research is required to specifically address both narrow and broad spectrum antibiotic use for late onset neonatal sepsis. Future research also needs to assess cost effectiveness and the impact of antibiotics in different settings such as developed or developing countries and lower gestational age groups.

Abstract
BACKGROUND Neonatal abstinence syndrome (NAS) due to opiate withdrawal may result in disruption of the mother-infant relationship, sleep-wake abnormalities, feeding difficulties, weight loss and seizures. Treatments used to ameliorate symptoms and reduce morbidity include opiates, sedatives and non-pharmacological treatments. OBJECTIVES To assess the effectiveness and safety of using a sedative compared to a non-opiate control for NAS due to withdrawal from opiates, and to determine which type of sedative is most effective and safe. SEARCH STRATEGY The standard search strategy of the Neonatal Review Group was used. This update included searches of the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 1, 2005), MEDLINE 1966-March 2005 and abstracts of conference proceedings. SELECTION CRITERIA Trials enrolling infants with NAS born to mothers with an opiate dependence, with > 80% follow up and using random or quasi-random allocation to sedative or control. Control could include another sedative or non-pharmacological treatment. DATA COLLECTION AND ANALYSIS Each author assessed study quality and extracted data independently. Primary outcomes included treatment failure (failure to achieve symptom control or use of additional drug treatment), seizure occurrence, mortality and neurodevelopment. Treatment effect was expressed using (RR), risk difference (RD), mean difference (MD) and weighted mean difference (WMD). Meta-analysis was performed using a fixed effect model. MAIN RESULTS Six studies enrolling a total of 305 patients met inclusion criteria (Coyle 2002; Finnegan 1984; Kahn 1969; Kaltenbach 1986; Khoo 1995; Madden 1977); however, two (Finnegan 1984; Kaltenbach 1986) may be sequential reports that include some identical patients. Methodological concerns included the use of quasi-random allocation methods in four studies, and sizeable, largely unexplained differences in reported numbers allocated to each group in three studies. Phenobarbitone compared to supportive care alone has not been shown to reduce treatment failure or time to regain birthweight (one study). However, the duration of supportive care given to infants was significantly reduced (MD -162.1 mins/day, 95% CI -249.2, -75.1). Comparing phenobarbitone to diazepam, meta-analysis of two studies found phenobarbitone produced a significant reduction in treatment failure (typical RR 0.39, 95% CI 0.24, 0.62). There was no significant difference in duration of treatment or hospital stay. Comparing phenobarbitone with chlorpromazine, one study found no significant difference in treatment failure rate. No data for neurodevelopment reported by treatment group of allocation were available. No trials were eligible that assessed clonidine for NAS. In infants treated with an opiate, a small quasi-random study reported a reduced severity of withdrawal. Infants were weaned from an opiate more quickly which allowed earlier hospital discharge and reduced hospital costs. These findings may reflect the low dose of opiate used for initial treatment and the policy of discharging infants home on phenobarbitone but not morphine. AUTHORS' CONCLUSIONS In newborn infants with NAS, there is no evidence that phenobarbitone compared with supportive care alone reduces treatment failure; however, phenobarbitone may reduce the daily duration of supportive care needed. Phenobarbitone, compared to diazepam, reduces treatment failure. In infants treated with an opiate, the addition of phenobarbitone may reduce withdrawal severity. Further trials are required to determine if this finding is applicable when a higher initial dose of opiate is used, and determine the effects of phenobabritone on infant development. There is insufficient evidence to support the use of chlorpromazine or clonidine in newborn infants with NAS. Clonidine and chlorpromazine should only be used in the context of a randomised clinical trial. This review should be taken in conjunction with the review "Opiate treatment for opiate withdrawal in newborn infants" (Osborn 2002a) which indicates that an opiate is the preferred initial therapy for NAS.

Treatments used to ameliorate symptoms and reduce morbidity include opiates, sedatives and non-pharmacological treatments. OBJECTIVES To assess the effectiveness and safety of using an opiate, compared to a sedative or non-pharmacological treatment, for treatment of NAS due to withdrawal from opiates. SEARCH STRATEGY The previous review was updated with additional searches of the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 1, 2005), MEDLINE (1966-December 2004) and EMBASE (1980-December 2004) supplemented by searches of conference abstracts and citation lists of published articles. SELECTION CRITERIA Trials enrolling infants with NAS born to mothers with an opiate dependence, with > 80% follow up and using random or quasi-random allocation to opiate or control. Control could include an opiate, sedative or non-pharmacological treatment. DATA COLLECTION AND ANALYSIS Each author assessed study quality and extracted data independently. Primary outcomes included control of symptoms, seizure occurrence, mortality and neurodevelopment. Treatment effect was expressed using relative risk (RR), risk difference (RD), mean difference (MD) and weighted mean difference (WMD). Meta-analysis was performed using a fixed effect model. MAIN RESULTS Seven studies enrolling a total of 585 infants met inclusion criteria (Carin 1983; Finnegan 1984; Jackson 2004; Kaltenbach 1986; Kandall 1983; Khoo 1995; Madden 1977); however, two (Finnegan 1984; Kaltenbach 1986) may be sequential reports that include some identical patients. The studies enrolled infants of mothers who had used opiates with or without other drugs during pregnancy. Methodological concerns included the use of quasi-random rather than random patient allocation methods in three studies; sizeable, largely unexplained differences in reported numbers allocated to each group in four studies; and imbalances in group characteristics after randomisation in one study. Opiate (morphine) vs supportive care only: One study (Khoo 1995) found no significant effect on treatment failure (RR 1.29, 95% CI 0.41, 4.07), a significant increase in hospital stay (MD 15.0 days, 95% CI 8.9, 21.1) and significant reductions in time to regain birthweight (MD -2.8 days, 95% -5.3, -0.3) and duration of supportive care (MD -197.2 minutes/day, 95% CI -274.2, -120.3). Opiate vs phenobarbitone: Meta-analysis of four studies found no significant difference in treatment failure (typical RR 0.76, 95% CI 0.51, 1.11). One of these studies (Finnegan 1984) reported that opiate treatment resulted in a significant reduction in treatment failure among infants of mothers who had used only opiates; however, as this was a post-hoc analysis, this result should be interpreted with caution. One study (Jackson 2004) reported a significant reduction in duration of treatment and admission to the nursery for infants receiving morphine compared to phenobarbitone. One study (Kandall 1983) reported a reduction in seizures, of borderline statistical significance, with the use of opiate. Opiate vs diazepam: Meta-analysis of two studies found a significant reduction in treatment failure (RR 0.43, 95% CI 0.23, 0.80) with the use of opiate. No study reported neurodevelopment by allocated treatment group. AUTHORS' CONCLUSIONS Opiates, as compared to supportive care only, appear to reduce the time to regain birth weight and reduce the duration of supportive care, but increase the duration of hospital stay; there is no evidence of effect on treatment failure. When compared to phenobarbitone, opiates may reduce the incidence of seizures but, overall, there is no evidence of effect on treatment failure. One study reported a reduction in duration of treatment and nursery admission for infants on morphine. When compared to diazepam, opiates reduce the incidence of treatment failure. A post-hoc analysis generates the hypothesis that treatment effects may vary according to whether the population includes infants born to all opiate users (i.e. with or without other drug exposure) or is restricted to infants of mothers who used opiates only. In view of the methodologic limitations of the included studies the conclusions of this review should be treated with caution.

Abstract
OBJECTIVE To develop an objective and reliable method to assess drug withdrawal in newborns by quantitatively estimating the amount of movement rather than scoring individual withdrawal signs. DESIGN In this cross sectional study, a commercial portable motion detector with computer memory, similar to a wrist watch (the actigraph) was used to measure movement. The measurements were compared with a clinical decision based on the neonatal abstinence syndrome (NAS) score. Movement was analysed, using non-parametric tests, in three groups: a control group of 10 infants, 13 opiate exposed newborns not treated for NAS, and 30 newborns treated for NAS (17 before treatment, eight within 24 hours of treatment, five when stabilised). RESULTS There were significant differences in the median activity score, expressed as counts per minute (cpm), in the pretreatment group (124 cpm) compared with the control (42 cpm, p < 0.0001), non-treated (74 cpm, p = 0.001), and stabilised treatment (75 cpm, p = 0.007) groups. The accuracy of the actigraph in the identification of newborns requiring treatment from those who did not was high compared with the clinical scores; sensitivity 94%; specificity 85%; positive and negative predictive values 88% and 92% respectively. CONCLUSIONS The measure of movement is comparable to the clinical score in the identification of newborns who require treatment and in determining the severity of withdrawal. The clear advantage of this method is its objectivity, reliability, and efficiency as a simple, non-invasive, bedside measure. Further evaluation in a randomised, controlled trial would establish comparative benefits, potential harms, safety, and acceptability.

Abstract
CONTEXT The perinatal mortality rate (PMR) in Macedonia is among the highest in Europe. The World Bank supported a consultant (HEJ) to collaborate with a Macedonian team to develop a national perinatal strategy with the goal of reducing the PMR. Education was given priority in the form of a hospital-based initiative to develop the capacity of health professionals to introduce evidence-based perinatal practice into 16 participating hospitals. A "train the teachers" approach was used, with trainees introduced to modern education and clinical practice in Sydney and subsequently supported to train their colleagues in Skopje. OBJECTIVES To describe the development, implementation and evaluation of the educational intervention. METHODS A curriculum, based on specific Macedonian needs, was developed in order to integrate teaching in the knowledge, skills and attitudinal domains of learning, using small group, interactive techniques. Twenty-five Macedonian doctors and nurses participated in 4-month (phase 1a) and 6-month (phase 1b) teaching programmes at a tertiary perinatal unit in Sydney. Australian staff conducted 4 2-week modules for 36 trainees in Macedonia (phase 2). The phase 1 trainees conducted 8 modules for 57 colleagues in Skopje (phase 3). The intervention was evaluated by trainee questionnaires, assessments of competence, changes in hospital practice and pre- (1997-99) and post-intervention (2000-01) comparisons of PMR. RESULTS A total of 115 doctors and nurses graduated from the programme. Positive responses to the education programme exceeded 80%. Evidence-based practice in 16 participating hospitals (covering 91% of all Macedonian births) was verified in 6 key areas of neonatology. The PMR fell significantly from 27.4 to 21.5 per 1000 births (RR 0.79, 95% CI 0.73, 0.85). The early neonatal death rate in babies weighing over 1000 g fell by 36%. CONCLUSIONS The intervention has increased the capacity of Macedonians to practise best-evidence perinatal medicine and improve outcomes. Sustainability is predicted by the "train the teachers" approach, with concurrent strengthening of the infrastructure and organisational framework.

Abstract
OBJECTIVE The purpose of this study was to determine, in a large preterm cohort (20-34 completed weeks of gestation), the incidence of histologic chorioamnionitis and the incidence of a histologic fetal response to chorioamnionitis (umbilical vasculitis with or without funisitis) in neonatal survivors (to 28 days) and perinatal deaths. STUDY DESIGN Placental histopathology was reviewed (n=3928 reports). In a subset of this cohort (n=2076 reports), evidence of a histologic fetal response was compared in neonatal survivors and perinatal deaths. RESULTS The incidence of histologic chorioamnionitis ranged from 66% at 20 to 24 weeks of gestation (n=261 neonates) to 16% at 34 weeks (n=770 neonates). The overall incidence was 31% (n=3928 neonates). At 25 to 29 weeks of gestation, neonatal survivors had a higher incidence of histologic chorioamnionitis (P=.02; 95% CI, 1.02-1.21). In addition, neonatal survivors had a higher incidence of a histologic fetal response to chorioamnionitis at 25 to 29 weeks of gestation (P=.01; 95%CI, 0.33-0.86) and 30 to 34 weeks of gestation (P=.02; 95%CI, 0.18-0.85). CONCLUSION Histologic chorioamnionitis is inversely related to gestational age. Both histologic chorioamnionitis and a histologic fetal response to chorioamnionitis were observed to be more common in preterm survivors of the neonatal period.

Abstract
OBJECTIVE To determine specific sleep characteristics in neonatal opiate withdrawal, referred to as the Neonatal Abstinence Syndrome (NAS), by measuring sleep efficiency, deprivation, disorganization and fragmentation in three groups: (i) healthy term neonates; (ii) opiate-exposed neonates who were treated for opiate withdrawal; and (iii) a group of opiate-exposed neonates who did not require treatment. METHODS A cohort study recording sleep patterns of neonates at 2-10 days of age (after 36 or more weeks of gestation) was carried out. Twenty-one neonates were exposed to opiates during pregnancy and 15 neonates were healthy controls. Sleep characteristics were predefined, and treated newborns were divided into early and stabilized treatment groups. Polygraphic recordings of sleep, movement and breathing were made continuously after a daytime feed. RESULTS Sleep deprivation, disorganization and fragmentation were found in newborns with NAS and were associated with the severity of the withdrawal. Neonates treated for NAS displayed increased wakefulness during early treatment (deprivation), but were similar to controls once stabilized. Both treated and non-treated groups had reduced amounts of quiet sleep (deprivation). Treated newborns showed an increase in indeterminate sleep (disorganization) and arousals-to-wakefulness (fragmentation). CONCLUSION This study determined the exact nature and degree of sleep disturbances in newborns during acute opiate withdrawal. The findings contribute to a further understanding of the physiology underlying neonatal opiate withdrawal and suggest that some changes in sleep are due to opiate withdrawal but others may reflect opiate dependency in utero.

The results of an ongoing trial of the addition of phenobarbital to an opiate are awaited.

OBJECTIVES To assess the effectiveness and safety of using an opiate, compared to a sedative or non-pharmacological treatment, for treatment of NAS due to withdrawal from opiates.

Abstract
1. In infants, promethazine has been implicated in the pathogenesis of sleep apnoea, apparent life threatening events (ALTE) and the Sudden Infant Death syndrome (SIDS). The aim of the present study was to investigate, in a neonatal animal, the effects of a commonly used promethazine-containing medication on airway protective mechanisms and cardiorespiratory reflexes following simulated gastro-oesophageal reflux (GER) to different levels in the oesophagus and pharynx. 2. Physiological and radiographic recordings were made in 21 naturally sleeping (controls) and 21 sedated (1.5 mg/kg, p.o., promethazine) piglets. On 3 consecutive days physiological recordings were made in all piglets during active sleep. Gastro-oesophageal reflux was simulated by the injection of boluses of 0.5 mL HCl, pH 2 or 3, or NaCl (0.9%) at 37 degrees C into the pharynx, upper or lower oesophagus. 3. In healthy neonatal piglets, minimal sedation with promethazine, which did not affect behaviour during wakefulness, revealed previously unreported findings during active sleep. 4. The most significant effects were observed following simulated GER to the pharynx, with no effect observed in the lower oesophagus. In sedated piglets, compared with naturally sleeping piglets, there was a significant reduction in swallowing (P < 0.01), delayed radiological clearance of fluid (P < 0.05), a reduction in breathing rate, oxygen saturation and heart rate and an increase in apnoea. 5. These findings are consistent with a low dose of promethazine producing a significant attenuation of airway protective mechanisms and, thus, stimulation of the laryngeal chemoreflex. The results suggest a mechanism for the association observed between promethazine use and the occurrence of ALTE and SIDS. The results support continued caution and suggest the need for greater regulation of promethazine-containing medications in infants.
