RESUMEN
OBJECTIVES: The COVID-19 pandemic imposed many challenges on pregnant women, including rapid changes to antenatal care aimed at reducing the societal spread of the virus. This study aimed to assess how the pandemic affected perinatal mental health and other pregnancy and neonatal outcomes in a tertiary unit in Queensland, Australia. METHODS: This was a retrospective cohort study of pregnant women booked for care between March 2019 - June 2019 and March 2020 - June 2020. A total of 1984 women were included with no confirmed cases of COVID-19. The primary outcome of this study was adverse maternal mental health defined as an Edinburgh Postnatal Depression Scale score of ≥13 or an affirmative response to 'EPDS Question 10'. Secondary outcomes were preterm birth <37 weeks and <32 weeks, mode of birth, low birth weight, malpresentation in labour, hypertensive disease, anaemia, iron/vitamin B12 deficiency, stillbirth and a composite of neonatal morbidity and mortality. RESULTS: There were no differences in the primary perinatal mental health outcomes. The rates of composite adverse neonatal outcomes (27 vs. 34â¯%, p<0.001) during the pandemic were higher; however, there was no difference in perinatal mortality (p=1.0), preterm birth (p=0.44) or mode of delivery (p=0.38). CONCLUSIONS: Although there were no adverse consequences on maternal mental health during the pandemic, there was a concerning increase in neonatal morbidity potentially due to the altered model of maternity care implemented in the early COVID-19 pandemic.

INTRODUCTION: There are a variety of factors that contribute to the development of allergic diseases in children, including environmental exposures during the maternal prenatal period. It has been proposed that probiotic supplementation during pregnancy could be used as a possible preventative measure to target childhood allergic disease. METHODS: Participants from a previously conducted prospective double-blind randomised control trial of probiotics versus placebo study (Study of PRrobiotics IN Gestation) were sent electronic questionnaires to complete about their child, who are now between 3 and 7 years of age. Demographic data and rates of allergic diseases were compared between the two groups. RESULTS: One hundred and seven women responded to the questionnaires. Between the two groups, there was no difference in the frequency of allergic diseases, with similar rates of eczema, asthma, and hospital presentations seen. CONCLUSION: In this follow-up study, infants of mothers who were exposed to probiotics during their pregnancy do not appear to have any paediatric health advantages in terms of allergic diseases.

Vascular access devices play vital roles within neonatal care. We aimed to identify neonatal vascular access device insertion and management practices, and describe the incidence and risk factors for complication development. This is a prospective cohort study of neonates requiring vascular access devices over 3 months in an Australian quaternary-referral neonatal intensive care unit. In addition to describing current practices, primary outcomes were device failure, complications, and skin complications. Results are reported using descriptive statistics and with risk factors calculated via Cox proportional hazards regression. A total of 104 neonates required 302 vascular access devices, over 1375 catheter days. Peripheral intravenous catheters (PIVCs) were most used (n = 186; 62%), followed by umbilical venous catheters (n = 52; 17%). Insertion attempts were often undocumented; but for those recorded, 5% of devices (n = 15) required 4 attempts or more. Device failure occurred in 28% (n = 82), at an incidence rate of 62.5 per 1000 catheter days (95% confidence interval [CI] 49.7-75.9). Failure was most frequent in PIVCs (37%; n = 68), peripheral arterial catheters (33%; n = 2), and peripherally inserted central catheters (20%; n = 6). Infiltration and extravasation were the most frequent cause of PIVC failure (12%; n = 35). A birth weight less than 1500 g was associated with a significant decrease in PIVC failure (hazard ratio 0.58; 95% CI 0.34-0.99).

BACKGROUND: The World Health Organization recommends that infants should be exclusively breastfed for the first 6 months of life and that breastfeeding should continue for 2 years and beyond. Most women initiate breastfeeding, but many do not continue for the recommended duration. While midwife-led continuity of antenatal care is linked to improved mother and infant outcomes, the influence on breastfeeding duration has not been previously reviewed. RESEARCH AIM: To critically analyze the literature that compared midwife-led continuity of antenatal care with other models of care where researchers have measured breastfeeding duration beyond postpartum hospital discharge. METHODS: A systematic literature review with critical analysis was used to answer the research aim. We systematically searched and screened five databases for quantitative studies where researchers had reported breastfeeding duration beyond postpartum hospital discharge after midwife-led continuity of antenatal care, compared with another model of antenatal care. Methodological quality was assessed using tools from the Cochrane Collaboration (RoB2 and ROBINS-I). In total, nine studies met the inclusion criteria. RESULTS: Clear conclusions about the association between midwife-led continuity of antenatal care and breastfeeding duration were not found. The risk of bias within non-randomized studies ranged from serious to critical, and a judgement of "some concerns" of risk of bias in the one randomized study. CONCLUSION: To date, the question of whether midwife-led continuity of antenatal care improves breastfeeding duration has not been established. There has been a lack of consistency in definitions of breastfeeding and descriptions of models of care, which has weakened the evidence-based of literature reviewed.Our review protocol was registered with PROSPERO; although due to COVID-19, this registration was not checked for eligibility by the PROSPERO team (CRD42020151276). https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42020151276.

Admission of a preterm or sick full-term infant to the neonatal intensive care unit (NICU) is a stressful experience for parents. Indeed, the 'NICU experience' may constitute a traumatic event for parents, distinct from other birth-related trauma, leading to significant and ongoing posttraumatic stress disorder (PTSD) symptoms. However, the rates at which this outcome occurs are not well understood. This review aimed to identify the prevalence of PTSD in mothers and fathers of high-risk infants admitted to the NICU, specifically focusing on the NICU experience as the index trauma. The PRISMA-P: Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols were used to conduct this review. We searched PsycINFO, PubMed, Scopus, EMBASE, Web of Science, ProQuest Dissertations and Theses databases, and reference lists of included articles (1980-2021). Two independent reviewers screened titles and abstracts and conducted the full-text screening assessment. Of the 707 records identified, seven studies met the inclusion criteria. In this systematic review, PTSD symptomatology was assessed by self-report measures rather than a clinical interview. We identified significant variations in the methodologies and quality between studies, with a wide variation of reported prevalence rates of PTSD of 4.5-30% in mothers and 0-33% in fathers. Overall, the findings indicate that up to one-third of parents experience PTSD symptomatology related to the NICU experience. These results emphasize the importance of universal routine antenatal and postnatal screening for symptoms of PTSD to identify parents at risk of distress during the NICU experience and after discharge.Trial registration: The study protocol was registered with Prospero registration number CRD42020154548 on 28 April 2020.

BACKGROUND: Limited access to obstetrics and gynaecology (O&G) services in rural and remote Australia is believed to contribute to suboptimal birth outcomes. AIMS: To describe the characteristics of pregnancy aeromedical transfers, in-hospital outcomes, and patient access to O&G services, as compared to whole of Australia data. MATERIALS AND METHODS: We conducted a cohort study of women who required aeromedical retrieval for pregnancy-related issues between the 1 January 2015 and 31 December 2017. RESULTS: Hospital outcome data were collected on 2171 (65.2%) mothers and 2438 (100.0%) babies. The leading retrieval reason was threatened preterm labour and delivery (n = 883; 40.7%). Most patients were retrieved from rural and remote areas (n = 2224; 93.0%). Retrieved patients were significantly younger (28.0 vs 30.0 years, 95% CI 27.7-28.3), more likely to be overweight or obese (52.2% vs 45.1%, 95% CI 47.5-56.9) and to have smoked during their pregnancy (14.0% vs 9.9%, 95% CI 12.5-15.5) compared to Australian pregnant women overall. Over one-third of transferred women gave birth by Caesarean section (n = 812; 37.4%); the median gestational age at birth was 33.0 (95% CI 32.7-33.3) weeks. Early gestation is associated with low birth weights (median = 2579.5 g; 95% CI 2536.1-2622.9), neonatal resuscitation (35.4%, 95% CI 33.5-37.3), and special care nursery admission (41.2%, 95% CI 39.3-43.2). There were 42 (1.7%, 95% CI 1.2-2.2) stillbirths, which was significantly higher than seen Australia-wide (n = 6441; 0.7%). CONCLUSION: This study found that pregnant women retrieved by the Royal Flying Doctor Service were younger, with higher rates of obesity and smoking.

OBJECTIVE: Given the role of gut microbiota in regulating metabolism, probiotics administered during pregnancy might prevent gestational diabetes mellitus (GDM). This question has not previously been studied in high-risk overweight and obese pregnant women. We aimed to determine whether probiotics (Lactobacillus rhamnosus and Bifidobacterium animalis subspecies lactis) administered from the second trimester in overweight and obese women prevent GDM as assessed by an oral glucose tolerance test (OGTT) at 28 weeks' gestation. Secondary outcomes included maternal and neonatal complications, maternal blood pressure and BMI, and infant body composition. RESEARCH DESIGN AND METHODS: This was a double-blind randomized controlled trial of probiotic versus placebo in overweight and obese pregnant women in Brisbane, Australia. RESULTS: The study was completed in 411 women. GDM occurred in 12.3% (25 of 204) in the placebo arm and 18.4% (38 of 207) in the probiotics arm (P = 0.10). At OGTT, mean fasting glucose was higher in women randomized to probiotics (79.3 mg/dL) compared with placebo (77.5 mg/dL) (P = 0.049). One- and two-hour glucose measures were similar. Preeclampsia occurred in 9.2% of women randomized to probiotics compared with 4.9% in the placebo arm (P = 0.09). Excessive weight gain occurred in 32.5% of women in the probiotics arm (55 of 169) compared with 46% in the placebo arm (81 of 176) (P = 0.01). Rates of small for gestational age (<10th percentile) were 2.4% in the probiotics arm (5 of 205) and 6.5% in the placebo arm (13 of 199) (P = 0.042). There were no differences in other secondary outcomes. CONCLUSIONS: The probiotics used in this study did not prevent GDM in overweight and obese pregnant women.

BACKGROUND: Ketonuria may be associated with adverse fetal outcomes. This study aimed to determine the prevalence of ketonuria at three time points in pregnancy and to assess whether ketonuria correlates with a clinical indication for performing a urine test. METHODS: Women had fasting urinary ketone levels measured at 16 and 28 weeks gestation and random ketone levels measured close to 36 weeks gestation. All ketone levels in the third trimester were recorded along with the clinical indication for the test. RESULTS: One hundred and eighty-seven women were included in the study. Twenty-two per cent of women had ketonuria at either 16 or 28 weeks gestation and 8% at 36 weeks gestation. Ketonuria was significantly more likely if a test was performed for a clinical indication (p = 0.0002). CONCLUSION: Ketonuria in pregnancy is common affecting at least one in five women. Ketonuria is more common in women who have a clinical indication for performing a urine test.
RESUMEN
BACKGROUND: A pregnancy risk score system in popular use in provincial and rural Queensland to assist with the triage decisions regarding the appropriate facility for pregnancy care has been upgraded with more recently recognised pregnancy risk factors. AIMS: To review the usefulness of the revised pregnancy risk score system and the integrity of its continuing use. MATERIALS AND METHODS: 459 women attending regional/rural hospitals and 1963 women attending a major specialist hospital for their pregnancy care had a prospective risk score assessed, and the resulting score was examined in relationship to pregnancy outcomes. RESULTS: There was a statistically significant positive relationship between a risk score of eight or more and an adverse outcome and a statistically significant negative relationship between a risk score of zero or one and adverse outcomes. CONCLUSION: This study revalidates the risk score process for use in provincial and rural Queensland in delineating those women requiring care in a location with higher levels of clinical service capability. Women with a risk score of 8 or more have an increased likelihood of needing birth intervention and/or having an adverse neonatal outcome and should be recognised as needing the development of a multidisciplinary care plan and assessment in a facility that is appropriately resourced for their end of pregnancy care.

BACKGROUND: Obesity is increasing in the child-bearing population as are the rates of gestational diabetes. Gestational diabetes is associated with higher rates of Cesarean Section for the mother and increased risks of macrosomia, higher body fat mass, respiratory distress and hypoglycemia for the infant. Prevention of gestational diabetes through life style intervention has proven to be difficult. A Finnish study showed that ingestion of specific probiotics altered the composition of the gut microbiome and thereby metabolism from early gestation and decreased rates of gestational diabetes in normal weight women. In SPRING (the Study of Probiotics IN the prevention of Gestational diabetes), the effectiveness of probiotics ingestion for the prevention of gestational diabetes will be assessed in overweight and obese women. METHODS/DESIGN: SPRING is a multi-center, prospective, double-blind randomized controlled trial run at two tertiary maternity hospitals in Brisbane, Australia. Five hundred and forty (540) women with a BMI > 25.0 kg/m(2) will be recruited over 2 years and receive either probiotics or placebo capsules from 16 weeks gestation until delivery. The probiotics capsules contain > 1x10(9) cfu each of Lactobacillus rhamnosus GG and Bifidobacterium lactis BB-12 per capsule. The primary outcome is diagnosis of gestational diabetes at 28 weeks gestation. Secondary outcomes include rates of other pregnancy complications, gestational weight gain, mode of delivery, change in gut microbiome, preterm birth, macrosomia, and infant body composition. The trial has 80% power at a 5% 2-sided significance level to detect a >50% change in the rates of gestational diabetes in this high-risk group of pregnant women. DISCUSSION: SPRING will show if probiotics can be used as an easily implementable method of preventing gestational diabetes in the high-risk group of overweight and obese pregnant women.

BACKGROUND: Physical symptoms are common in pregnancy and are predominantly associated with normal physiological changes. These symptoms have a social and economic cost, leading to absenteeism from work and additional medical interventions. There is currently no simple method for identifying common pregnancy related problems in the antenatal period. A validated tool, for use by pregnancy care providers would be useful. The aim of this study was to develop and validate a Pregnancy Symptoms Inventory for use by health professionals. METHODS: A list of symptoms was generated via expert consultation with health professionals. Focus groups were conducted with pregnant women. The inventory was tested for face validity and piloted for readability and comprehension. For test-re-test reliability, the tool was administered to the same women 2 to 3 days apart. Finally, midwives trialled the inventory for 1 month and rated its usefulness on a 10cm visual analogue scale (VAS). RESULTS: A 41-item Likert inventory assessing how often symptoms occurred and what effect they had, was developed. Individual item test re-test reliability was between .51 to 1, the majority (34 items) scoring ≥0.70. The top four "often" reported symptoms were urinary frequency (52.2%), tiredness (45.5%), poor sleep (27.5%) and back pain (19.5%). Among the women surveyed, 16.2% claimed to sometimes or often be incontinent. Referrals to the incontinence nurse increased > 8 fold during the study period. CONCLUSIONS: The PSI provides a comprehensive inventory of pregnancy related symptoms, with a mechanism for assessing their effect on function. It was robustly developed, with good test re-test reliability, face validity, comprehension and readability. This provides a validated tool for assessing the impact of interventions in pregnancy.

BACKGROUND: Overweight and obesity are associated with increased risk for pregnancy complications. Knowledge about increased risks in overweight and obese women could contribute to successful prevention strategies and the aim of this study is to assess current levels of knowledge in a pregnant population. METHODS: Cross sectional survey of 412 consecutive unselected women in early pregnancy in Brisbane, Australia: 255 public women attending their first antenatal clinic visit and 157 women at private maternal fetal medicine clinics undergoing a routine ultrasound evaluation prior to 20 weeks gestation. The cohort was stratified according to pre pregnancy BMI (< 25.0 or ≥ 25.0). The main outcome measure was knowledge regarding the risks of overweight and obesity in pregnancy. RESULTS: Over 75% of respondents identified that obese women have an increased risk of overall complications, including gestational diabetes and hypertensive disorders of pregnancy compared to women of normal weight. More than 60% of women asserted that obesity would increase the risk of caesarean section and less than half identified an increased risk of adverse neonatal outcomes. Women were less likely to know about neonatal complications (19.7% did not know about the effect of obesity on these) than maternal complications (7.4%). Knowledge was similar amongst women recruited at the public hospital and those recruited whilst attending for an ultrasound scan at a private clinic. For most areas they were also similar between women of lower and higher BMI, but women with BMI < 25.0 were less likely to know that obesity was associated with increased rate of Caesarean section than those with higher BMI (16.8% versus 4.5%, P < 0.001). Higher educational status was associated with more knowledge of the risks of overweight and obesity in pregnancy. CONCLUSIONS: Many women correctly identify that overweight and obesity increases the overall risk of complications of pregnancy and childbirth. The increased risks of maternal complications associated with being obese are better known than the increased risk of neonatal complications. Maternal education status is a main determinant of the extent of knowledge and this should be considered when designing education campaigns.

BACKGROUND: Physical activity may reduce the risk of adverse maternal outcomes, yet there are very few studies that have examined the correlates of exercise amongst obese women during pregnancy. We examined which relevant sociodemographic, obstetric, and health behaviour variables and pregnancy symptoms were associated with exercise in a small sample of obese pregnant women. METHODS: This was a secondary analysis using data from an exercise intervention for the prevention of gestational diabetes in obese pregnant women. Using the Pregnancy Physical Activity Questionnaire (PPAQ), 50 obese pregnant women were classified as "Exercisers" if they achieved ≥ 900 kcal/wk of exercise and "Non-Exercisers" if they did not meet this criterion. Analyses examined which relevant variables were associated with exercise status at 12, 20, 28 and 36 weeks gestation. RESULTS: Obese pregnant women with a history of miscarriage; who had children living at home; who had a lower pre-pregnancy weight; reported no nausea and vomiting; and who had no lower back pain, were those women who were most likely to have exercised in early pregnancy. Exercise in late pregnancy was most common among tertiary educated women. CONCLUSIONS: Offering greater support to women from disadvantaged backgrounds and closely monitoring women who report persistent nausea and vomiting or lower back pain in early pregnancy may be important. The findings may be particularly useful for other interventions aimed at reducing or controlling weight gain in obese pregnant women.

OBJECTIVE: To examine the feasibility of an individualized exercise program to prevent gestational diabetes mellitus (GDM) in obese pregnant women. RESEARCH DESIGN AND METHODS: The study was a pilot randomized controlled trial with obese pregnant women (intervention group, individualized exercise program [n = 25]; control group, usual care [n = 25]). Average weekly energy expenditure (MET hours per week and kilocalories per week) of exercise-specific activity was assessed during pregnancy using the Pregnancy Physical Activity Questionnaire. Fasting glucose and insulin and homeostasis model assessment of insulin resistance (HOMA-IR) were assessed at baseline and 20, 28, and 36 weeks' gestation. RESULTS: Of the women in the intervention group, 16 of 22 (73%) achieved more than 900 kcal/week of exercise-based activity at 28 weeks compared with 8 of 19 women in the control group (42%), P = 0.047. However, insulin resistance (HOMA-IR) did not differ between the groups. CONCLUSION: This intervention was feasible and prompted a modest increase in physical activity. However, we are not confident that this intervention would be sufficient to prevent GDM.
