Journal Article A study protocol for live and deceased donor uterus transplantation as a treatment for women with uterine factor infertility.(2024-03-27) ;Pittman, Jana ;Brännström, Mats ;Keily, Neill ;Gerstl, Brigitte ;Cavazzoni, Elena ;Pleass, Henry ;Lotz, Mianna ;Rogers, Natasha ;Wong, Germaine ;Hsueh, Wayne; ;Abbott, Jason ADeans, RebeccaUterus transplantation (UTx) is an emerging treatment option for women with uterine factor infertility (UFI) or the absence of a functional uterus. This is the study protocol for the first human UTx clinical trial in Australia.This protocol outlines the approved training program used to plan, diagnose, screen, and treat patients who may be eligible for UTx using living and deceased donors. This multi-site clinical research study includes three tertiary hospital sites within New South Wales (NSW), Australia - Prince of Wales, Royal Hospital for Women and Westmead Hospitals. Our UTx protocol is based on that used by our collaborative partner, the inaugural UTx team in Gothenburg, Sweden. The Swedish UTx team provides ongoing preceptorship for the Australian UTx team. Ethics approval for six UTx procedures using living or deceased donors (Western Sydney Local Health District Human Research Ethics Committee: 2019/ETH138038) was granted in 2020.Results from surgeries and live births will be published. Data will be prospectively entered into the registry of the International Society of Uterus Transplantation (ISUTx), a sub-section of The Transplantation Society (TTS).ACTRN12622000917730.A multidisciplinary research team has been formed between three tertiary hospitals in Sydney - The Royal Hospital for Women, Prince of Wales and Westmead Hospitals; and with the Swedish UTx, University of Gothenburg. The Swedish team pioneered animal and human UTx studies since 1998, including publishing the first live birth after UTx. (1) This Australian trial commenced in January 2023.Uterus transplantation gives women with UFI the opportunity to be gestational and genetic mothers. It is a complex procedure for both the donor and recipient, with medical and surgical risks. An extensive multidisciplinary approach is required to optimise patient safety and graft outcomes. This protocol outlines our Australian UTx team strategy for screening, recruitment, surgical approach, and clinical management of UTx recipients and donors. - Publication
Journal Article A descriptive study of domestic and family violence presentations to an emergency department in the Northern Territory.(2024-04-21); ; ; ; Kault, DavidExamine the nature of domestic and family violence (DFV) presentations to an ED in the Northern Territory and identify potential gaps in service delivery.Prospective descriptive study of DFV presentations in November 2021.A total of 70 presentations were identified, representing 1.2% of all presentations aged 16 years and older. Disproportionately impacted were First Nations people (90%), women (77.1%) and those aged less than 40 years (67.1%). Most (81.4%) arrived outside of business hours and only 37.1% were assessed by the social worker. Case complexity was increased by high rates of homelessness (30%), concurrent alcohol consumption (44.3%) and pregnancy (11.1% of females). More than a third (37.1%) had attended on one to four occasions in the previous 6 months with a DFV-related injury. Compared to non-DFV attendances, the median ED length of stay was approximately twice as long (456 vs 210 min), admissions rates to the ED short stay unit five times higher (25.7% vs 5.7%; P < 0.01, odds ratio [OR] = 5.7 and 95% confidence interval [CI] = 3.3-9.8) and rates of self-discharge prior to completion of care 9 times higher (12.9% vs 1.5%; P < 0.01, OR = 9.5 and 95% CI = 4.6-19.7).The data highlights the need for a 24 h trauma-informed, culturally safe and integrated service to support people experiencing DFV. This could be achieved by a specialist unit designed and staffed by First Nations health practitioners. - Publication
Journal Article Ascertainment of Aboriginal and Torres Strait Islander status for assessment of perinatal health outcomes: Reported versus derived maternal ethnicity in Western Australian pregnancy data.(2024-06-04) ;Berman, Ye'elah E ;Newnham, John P ;Ward, Sarah V; Doherty, Dorota AUnder-identification of Aboriginal and Torres Strait Islander (hereafter referred to as Aboriginal) people can result in inaccurate estimation of health outcomes. Data linkage has improved identification of Aboriginal people in administrative datasets.To compare three methods of ascertainment of Aboriginal status using only pregnancy data from the Western Australian Midwives Notification System (MNS), to the linked Indigenous Status Flag (ISF) derived by the Department of Health.This retrospective population-based cohort study utilised logistic regression to determine which demographic characteristics were associated with under-identification, and the effect of ascertainment method on perinatal adverse outcomes.All methods identified a core group of 19 017 (83.0%) Aboriginal women and the ISF identified 2298 (10.0%) women who were not identified using any other method. Under-ascertainment was lowest when a woman's Aboriginal status was determined by ever being recorded as Aboriginal in the MNS data, and highest when taken as it had been recorded for the birth in question. Maternal age <20 years, smoking during pregnancy, pre-existing diabetes, a history of singleton preterm birth and being in the lowest 20% of Socio-Economic Indexes for Areas score were all associated with a higher chance of being identified by the methods using only the MNS. These methods were less likely to identify nulliparous women, and those with maternal age ≥35 years. The method of ascertainment of Aboriginality did not make a significant difference to the adjusted predicted marginal probabilities of adverse perinatal outcomes.Unlinked pregnancy data can be used for epidemiological research in Aboriginal obstetric populations. - Publication
Journal Article Association between maternal mental health-related hospitalisation in the 5 years prior to or during pregnancy and adverse birth outcomes: a population-based retrospective cohort data linkage study in the Northern Territory of Australia.(2024-04-30) ;Dadi, Abel Fekadu ;He, Vincent; ;Hazell-Raine, Karen ;Reilly, Nicole ;Giallo, Rebecca ;Rae, Kym M ;Hazell, PhilipGuthridge, StevenMental health conditions prior to or during pregnancy that are not addressed can have adverse consequences for pregnancy and birth outcomes. This study aimed to determine the extent to which women's mental health-related hospitalisation (MHrH) prior to or during pregnancy was associated with a risk of adverse birth outcomes.We linked the perinatal data register for all births in the Northern Territory, Australia, from the year 1999 to 2017, to hospital admissions records to create a cohort of births to women aged 15-44 years with and without MHrH prior to or during pregnancy. We used Modified Poisson Regression and Latent Class Analysis to assess the association between maternal MHrH and adverse birth outcomes (i.e., stillbirth, preterm birth, low birth weight, and short birth length). We explored a mediation effect of covariates on theoretical causal paths. We calculated the adjusted Population Attributable Fraction (PAF) and Preventive Fractions for the Population (PFP) for valid associations.From 72,518 births, 70,425 births (36.4% for Aboriginal women) were included in the analysis. The Latent Class Analys identified two classes: high (membership probability of 10.5%) and low adverse birth outcomes. Births to Aboriginal women with MHrH were around two times more likely to be in the class of high adverse birth outcomes. MHrH prior to or during pregnancy increased the risk of all adverse birth outcomes in both populations with risk ranging from 1.19 (95% CI: 1.05, 1.35) to 7.89 (1.17, 53.37). Eight or more antenatal care visits and intrauterine growth restriction mostly played a significant mediation role between maternal MHrH and adverse birth outcomes with mediation effects ranging from 1.04 (1.01, 1.08) to 1.39 (1.14, 1.69). MHrH had a low to high population impact with a PAF ranging from 16.1% (5.1%, 25.7%) to 87.3% (14.3%, 98.1%). Eight or above antenatal care visits avert extra adverse birth outcomes that range from 723 (332-765) stillbirths to 3003 (1972-4434) preterm births.Maternal MHrH is a modifiable risk factor that explained a low to moderate risk of adverse birth outcomes in the Northern Territory. The knowledge highlights the need for the development and implementation of preconception mental health care into routine health services.The Child and Youth Development Research Partnership (CYDRP) data repository is supported by a grant from the Northern Territory Government. - Publication
Journal Article Impact on pregnancy outcomes of intermittent preventive treatment with sulfadoxine-pyrimethamine in urban and peri-urban Papua New Guinea: a retrospective cohort study.(2024-07-05) ;Cellich, Philip; ;Rogerson, Stephen JMola, Glen D LIntermittent preventive treatment in pregnancy with sulfadoxine-pyrimethamine (IPTp-SP) reduces malaria-attributable adverse pregnancy outcomes and may also prevent low birth weight (< 2,500 g) through mechanisms independent of malaria. Malaria transmission in Papua New Guinea (PNG) is highly heterogeneous. The impact of IPTp-SP on adverse birth outcomes in settings with little or no malaria transmission, such as PNG's capital city Port Moresby, is unknown.A retrospective cohort study was conducted amongst HIV-negative women with a singleton pregnancy who delivered at Port Moresby General Hospital between 18 July and 21 August 2022. The impact of IPTp-SP doses on adverse birth outcomes and anaemia was assessed using logistic and linear regression models, as appropriate.Of 1,140 eligible women amongst 1,228 consecutive births, 1,110 had a live birth with a documented birth weight. A total of 156 women (13.7%) did not receive any IPTp-SP, 347 women (30.4%) received one, 333 (29.2%) received two, and 304 (26.7%) received the recommended ≥ 3 doses of IPTp-SP. A total of 65 of 1,110 liveborn babies (5.9%) had low birth weight and there were 34 perinatal deaths (3.0%). Anaemia (haemoglobin < 100 g/L) was observed in 30.6% (243/793) of women, and 14 (1.2%) had clinical malaria in pregnancy. Compared to women receiving 0-1 dose of IPTp-SP, women receiving ≥ 2 doses had lower odds of LBW (adjusted odds ratio [aOR] 0.50; 95% confidence interval [CI] 0.26, 0.96), preterm birth (aOR 0.58; 95% CI 0.32, 1.04), perinatal death (aOR 0.49; 95% CI 0.18, 1.38), LBW/perinatal death (aOR 0.55; 95% CI 0.27, 1.12), and anaemia (OR 0.50; 95% CI 0.36, 0.69). Women who received 2 doses versus 0-1 had 45% lower odds of LBW (aOR 0.55, 95% CI 0.27, 1.10), and a 16% further (total 61%) reduction with ≥ 3 doses (aOR 0.39, 95% CI 0.14, 1.05). Birth weights for women who received 2 or ≥ 3 doses versus 0-1 were 81 g (95% CI -3, 166) higher, and 151 g (58, 246) higher, respectively.Provision of IPTp-SP in a low malaria-transmission setting in PNG appears to translate into substantial health benefits, in a dose-response manner, supporting the strengthening IPTp-SP uptake across all transmission settings in PNG. - Publication
Journal Article Assessing the Role of Echocardiography in Pregnancy in First Nations Australian Women: Is It an Underutilised Resource?(2024-06-25) ;Marangou, James ;Ferguson, Dominic; ;Kaethner, Alexander; ; Rheumatic heart disease (RHD) remains prevalent within First Nations Australian communities. RHD is more common in females and peak prevalence corresponds with childbearing age. Significant valvular disease can complicate pregnancy. Current practice in Northern Australia is to refer pregnant women for echocardiography if there are signs or symptoms of possible cardiac pathology or a history of acute rheumatic fever (ARF) or RHD. It is not currently routine practice to offer echocardiographic screening for all pregnant women at high risk of RHD.This study aimed to assess the current referral practices for echocardiography and disease patterns in pregnant women in the Northern Territory, Australia-a region with a known high prevalence of RHD in the First Nations population.A retrospective analysis of all echocardiography referrals of pregnant women over a 4-year period was performed. Data included indication for echocardiography, clinical history, echocardiographic findings, and location of delivery. Comparisons were made using Fisher's exact and Mann-Whitney U tests.A total of 322 women underwent echocardiography during pregnancy: 195 First Nations and 127 non-Indigenous women (median age, 25 vs 30 years, respectively; p<0.01). Indications for echocardiography differed by ethnicity, with history of ARF or RHD being the most common indication in First Nations women, and incidental murmur the most common in non-Indigenous women. First Nations women were more likely to have abnormal echocardiograms (35.9% vs 11.0% in non-Indigenous women; p<0.01) or a history of ARF or RHD (39.4% vs 0.8%; p<0.01), but less likely to have documented cardiac symptoms as an indication for echocardiography (8.2% vs 20.5%; p<0.01). New cardiac diagnoses were made during pregnancy in 11 (5.6%) First Nations and two (1.6%) non-Indigenous women (p=0.02). Moderate or severe valve lesions were detected in 26 (13.3%) First Nations women (all previously diagnosed), and 11 (5.6%) had previous cardiac surgery. No severe valve lesions were identified in the non-Indigenous group. Interstate transfer to a tertiary centre with valve intervention services was required during pregnancy or the puerperium for 12 (6.2%) First Nations women and no non-Indigenous women.Amongst pregnant women in the Northern Territory who had an indication for echocardiography, First Nations women were more likely to have abnormal echocardiograms. This was mainly due to valvular disease secondary to RHD. Cardiac symptoms were infrequently recorded as an indication for echocardiography in First Nations women, suggesting possible underappreciation of symptoms. Having a low threshold for echocardiographic investigation, including consideration of universal screening during pregnancy, is important in a high RHD-burden setting such as ours. A better understanding of the true prevalence and spectrum of disease severity in this population would enable health services to invest in appropriate resources. - Publication
Journal Article Fetal sex and risk of pregnancy-associated malaria in Plasmodium falciparum-endemic regions: a meta-analysis.(2023-06); ;Hadiprodjo, A ;Gutman, J ;Briand, V ;Fievet, N ;Valea, I ;Tinto, H ;D'Alessandro, U ;Landis, S ;Ter Kuile, F ;Ouma, P ;Oneko, M ;Mwapasa, V ;Slutsker, L ;Terlouw, D ;Kariuki, S ;Ayisi, J ;Nahlen, B ;Desai, M ;Madanitsa, M ;Kalilani-Phiri, L ;Ashorn, P ;Maleta, K ;Tshefu-Kitoto, A ;Mueller, I ;Stanisic, D ;Cates, J ;Van Eijk, A ;Ome-Kaius, M ;Aitken, ERogerson, SIn areas of moderate to intense Plasmodium falciparum transmission, malaria in pregnancy remains a significant cause of low birth weight, stillbirth, and severe anaemia. Previously, fetal sex has been identified to modify the risks of maternal asthma, pre-eclampsia, and gestational diabetes. One study demonstrated increased risk of placental malaria in women carrying a female fetus. We investigated the association between fetal sex and malaria in pregnancy in 11 pregnancy studies conducted in sub-Saharan African countries and Papua New Guinea through meta-analysis using log binomial regression fitted to a random-effects model. Malaria infection during pregnancy and delivery was assessed using light microscopy, polymerase chain reaction, and histology. Five studies were observational studies and six were randomised controlled trials. Studies varied in terms of gravidity, gestational age at antenatal enrolment and bed net use. Presence of a female fetus was associated with malaria infection at enrolment by light microscopy (risk ratio 1.14 [95% confidence interval 1.04, 1.24]; P = 0.003; n = 11,729). Fetal sex did not associate with malaria infection when other time points or diagnostic methods were used. There is limited evidence that fetal sex influences the risk of malaria infection in pregnancy.2437 - Publication
Journal Article The health and educational costs of preterm birth to 18 years of age in Australia.(2021-07-15) ;Newnham, John P ;Schilling, Chris ;Petrou, Stavros ;Morris, Jonathan M ;Wallace, Euan M; ;Edwards, Lindsay ;Skubisz, Monika M ;White, Scott W ;Rynne, Brendan ;Arrese, Catherine ADoherty, Dorota ABACKGROUND: Preterm birth is the greatest cause of death up to five years of age and an important contributor to lifelong disability. There is increasing evidence that a meaningful proportion of early births may be prevented, but widespread introduction of effective preventive strategies will require financial support. AIMS: This study estimated the economic cost to the Australian government of preterm birth, up to 18 years of age. MATERIALS AND METHODS: A decision-analytic model was developed to estimate the costs of preterm birth in Australia for a hypothetical cohort of 314 814 children, the number of live births in 2016. Costs to Australia's eight jurisdictions included medical expenditures and additional costs to educational services. RESULTS: The total cost of preterm birth to the Australian government associated with the annual cohort was estimated at $1.413 billion (95% CI 1047-1781). Two-thirds of the costs were borne by healthcare services during the newborn period and one-quarter of the costs by educational services providing special assistance. For each child, the costs were highest for those born at the earliest survivable gestational age, but the larger numbers of children born at later gestational ages contributed heavily to the overall economic burden. CONCLUSION: Preterm birth leaves many people with lifelong disabilities and generates a significant economic burden to society. The costs extend beyond those to the healthcare system and include additional educational needs. Assessments of economic costs should inform economic evaluations of interventions aimed at the prevention or treatment of preterm birth.1229 - Publication
Case Reports Management of grade V splenic injury with splenic artery embolization in pregnancy: A case report.(2022-01-30) ;Ragunathan, KumaressanINTRODUCTION: Trauma is known to be a causative factor of mortality in pregnancy. However, splenic injuries are atypical in pregnancy. In this case report, we discuss a novel approach using splenic artery embolization to manage a severe form of splenic injury in pregnancy. CASE PRESENTATION: A 35-year-old multigravida presented at 28 weeks of gestation. She had sustained grade V splenic injury and was treated with splenic artery embolization. She continued her pregnancy up to term following the treatment. DISCUSSION: Splenic artery embolization should be considered as an alternative to laparotomy in managing severe forms of splenic injury in pregnancy.2075 - Publication
Journal Article Birth outcomes in women with gestational diabetes managed by lifestyle modification alone: The PANDORA Study.(2019-10-03) ;Cheng E ;Longmore D ;Barzi F ;Barr ELM ;Lee I; ;Boyle JA ;Oats J; ;McIntyre HD ;Kirkwood M ;Dempsey K ;Zhang X; ; ;Zimmet P ;Brown ADH ;Shaw JETo assess outcomes of women in the Pregnancy and Neonatal Diabetes Outcomes in Remote Australia (PANDORA) cohort with gestational diabetes mellitus (GDM) managed by lifestyle modification compared with women without hyperglycaemia in pregnancy. Indigenous (n=97) and Europid (n=113) women managed by lifestyle modification were compared to women without hyperglycaemia (n=235). Multivariate linear and logistic regressions assessed whether GDM-lifestyle women had poorer outcomes compared to women without hyperglycaemia. Women with GDM-lifestyle had higher body mass index and lower gestational weight gain than women without hyperglycaemia. On univariate analysis, gestational age at delivery was lower and induction rates were higher in women with GDM-lifestyle than without hyperglycaemia. On multivariable regression, GDM-lifestyle was associated with lower gestational age at delivery (by 0.73 weeks), lower birthweight z-score (by 0.26, p=0.007), lower likelihood of large for gestational age (LGA) [OR (95% CI): 0.55 (0.28, 1.02), p=0.059], and greater likelihood of labour induction [2.34 (1.49, 3.66), p < 0.001] than women without hyperglycaemia CONCLUSION: Women with GDM managed by lifestyle modification had higher induction rates and their offspring had lower birthweight z-scores, with a trend to lower LGA than those without hyperglycaemia in pregnancy. Further studies are indicated to explore reasons for higher induction rates.4096
