Reports of rising stillbirth rates in Australia have generated concern among affected parents and other stakeholders. Review of the national data suggests that much of the rise is being driven by an increase in terminations of pregnancy after 20 weeks' gestation. This increase coincides with legislative changes expanding access to terminations beyond 20 weeks. Alongside publishing stillbirth rates according to the legal definition (stillbirths from 20 weeks' gestation including terminations of pregnancy), national reporting bodies should routinely publish stillbirth rates among births from 28 weeks' gestation excluding terminations of pregnancy as the latter is most relevant to Australia's current stillbirth prevention initiatives.
Background Stillbirths impact over two million parents globally every year. Despite current knowledge, technology, and investigations, many stillbirths remain unexplained and are not fully investigated. An important step forward in addressing this gap is determining which investigations produce the highest utility in identifying the cause of death (COD).Aims The objective of this study is to identify and define the usefulness or utility of investigations in determining COD among a cohort of stillbirths.Materials and Methods Prospective cohort study from 2013 to 2018 comprising 695 stillbirths. An expert panel blinded to COD assessed the clinical utility of investigations using a purpose-built tool. A stepwise approach was applied, categorising investigations into three groups: clinical and laboratory investigations; placental pathology; and autopsy examination. Clinical utility of the investigations was defined as the proportion of cases in which each test contributed to the identification of the COD.Results Placental pathology had the highest clinical utility (87%), followed by comprehensive maternal history (82%), genetic analysis (75%), maternal blood investigations for infection (64%), fetal-maternal haemorrhage (FMH) (57%), and fetal autopsy (47%). Placental pathology and genetic analysis were useful across all clinical scenarios, while autopsy was most beneficial when the clinical scenario was unknown. A COD was established in 528 cases (76%), with 310 cases (47%) identified post-placental examination.Conclusions The investigations with the highest clinical utility were placental pathology, comprehensive maternal history, genetic analysis, maternal blood investigations, FMH, and fetal autopsy. This study supports a core set of investigations, supplemented by selective tests based on the clinical scenario.
(Abstracted from Paediatr Perinat Epidemiol 2025;39:198–204) Worldwide, nearly 2 million stillbirths occur every year. According to the 2011 and 2016 Lancet Stillbirths series, an estimated 20% to 40% were preventable.
Background and AimPeople with new-onset diabetes mellitus (diabetes) could be a possible target population for pancreatic cancer surveillance. However, distinguishing diabetes caused by pancreatic cancer from type 2 diabetes remains challenging. We aimed to develop and validate a model to predict pancreatic cancer among women with new-onset diabetes.MethodsWe conducted a retrospective cohort study among Australian women newly diagnosed with diabetes, using first prescription of anti-diabetic medications, sourced from administrative data, as a surrogate for the diagnosis of diabetes. The outcome was a diagnosis of pancreatic cancer within 3 years of diabetes diagnosis. We used prescription medications, severity of diabetes (i.e., change/addition of medication within 2 months after first medication), and age at diabetes diagnosis as potential predictors of pancreatic cancer.ResultsAmong 99 687 women aged >= 50 years with new-onset diabetes, 602 (0.6%) were diagnosed with pancreatic cancer within 3 years. The area under the receiver operating curve for the risk prediction model was 0.73. Age and diabetes severity were the two most influential predictors followed by beta-blockers, acid disorder drugs, and lipid-modifying agents. Using a risk threshold of 50%, sensitivity and specificity were 69% and the positive predictive value (PPV) was 1.3%.ConclusionsOur model doubled the PPV of pancreatic cancer in women with new-onset diabetes from 0.6% to 1.3%. Age and rapid progression of diabetes were important risk factors, and pancreatic cancer occurred more commonly in women without typical risk factors for type 2 diabetes. This model could prove valuable as an initial screening tool, especially as new biomarkers emerge.
Background: Deterioration of glycaemic control in people with long-standing diabetes mellitus (diabetes) may be a possible indicator of pancreatic cancer. However, the magnitude of the association between diabetes deterioration and pancreatic cancer has received little attention. Methods: We conducted a matched cohort study, nested within a population-based cohort of Australian women with diabetes. Women with unstable diabetes, defined as a change in medication after a 2-year period of stable medication use, were matched by birth year to those with stable diabetes, in a 1:4 ratio. We used flexible parametric survival models to estimate hazard ratios (HRs) and 95% confidence intervals (CI). Results: We included 134,954 and 539,789 women in the unstable and stable diabetes cohorts, respectively (mean age 68 years). In total, 1,315 pancreatic cancers were diagnosed. Deterioration of stable diabetes was associated with a 2.5-fold increased risk of pancreatic cancer (HR 2.55; 95% CI 2.29 -2.85). The risk was particularly high within the first year after diabetes deteriorated. HRs at 3 months, 6 months and 1 year were: 5.76 (95% CI 4.72-7.04); 4.56 (95% CI 3.81-5.46); and 3.33 (95% CI 2.86-3.89), respectively. The risk was no longer significantly different after 7 years. Conclusions: Deterioration in glycaemic control in people with previously stable diabetes may be an indicator of pancreatic cancer, suggesting investigations of the pancreas may be appropriate. The weaker longer-term (3-7 years) association between diabetes deterioration and pancreatic cancer may indicate that poor glycaemic control can be a risk factor for pancreatic cancer.

BackgroundDelayed reporting of decreased fetal movements (DFM) could represent a missed opportunity to prevent stillbirth. Mobile phone applications (apps) have the potential to improve maternal awareness and reporting of DFM and contribute to stillbirth prevention. AimsTo evaluate the effectiveness of the My Baby's Movements (MBM) app on late-gestation stillbirth rates. Materials and MethodsThe MBM trial evaluated a multifaceted fetal movements awareness package across 26 maternity services in Australia and New Zealand between 2016 and 2019. In this secondary analysis, generalised linear mixed models were used to compare rates of late-gestation stillbirth, obstetric interventions, and neonatal outcomes between app users and non-app users including calendar time, cluster, primiparity and other potential confounders as fixed effects, and hospital as a random effect. ResultsOf 140 052 women included, app users comprised 9.8% (n = 13 780). The stillbirth rate was not significantly lower among app users (1.67/1000 vs 2.29/1000) (adjusted odds ratio (aOR) 0.79; 95% CI 0.51-1.23). App users were less likely to have a preterm birth (aOR 0.81; 0.75-0.88) or a composite adverse neonatal outcome (aOR 0.87; 0.81-0.93); however, they had higher rates of induction of labour (IOL) (aOR 1.27; 1.22-1.32) and early term birth (aOR 1.08; 1.04-1.12). ConclusionsThe MBM app had low uptake and its use was not associated with stillbirth rates but was associated with some neonatal benefit, and higher rates of IOL and early term birth. Use and acceptability of tools designed to promote fetal movement awareness is an important knowledge gap. The implications of increased IOL and early term births warrant consideration in future studies.
BackgroundUp to 20% of all stillbirths and 45% of term stillbirths are currently classified as unexplained. Many of these stillbirths do not undergo currently recommended investigations. This may leave questions unanswered and not identify stillbirths with a recurrence risk in subsequent pregnancies. AimsTo validate a new tool (Stillbirth Investigation Utility Tool) to identify the clinical utility of investigations in stillbirth and the inter-rater agreement on cause of stillbirth using the Perinatal Society of Australia and New Zealand-Perinatal Death Classification (PSANZ-PDC). Materials and methodsThirty-four stillbirths were randomly selected for inclusion, each assessed independently by five blinded assessors. The investigations were grouped into three categories: clinical and laboratory; placental pathology; and autopsy examination. The cause of death was assigned at the end of each group. Outcome measures were clinical utility of investigations measured by assessor rated usefulness and inter-rater agreement on the assigned cause of death. ResultsComprehensive maternal history, maternal full blood count, maternal blood group and screen and placenta histopathology were useful in all cases. Clinical photographs were not performed and should have been performed in 50% of cases. The inter-rater agreement on cause of death assigned after all investigation results was 0.93 (95% CI 0.87-1.0). ConclusionsThe new Stillbirth Investigation Utility Tool showed very good agreement in assigning the cause of death using PSANZ-PDC. Four investigations were useful in all cases. Minor refinements will be made based on feedback to enhance usability for wider implementation in research studies to assess the yield of investigations in stillbirths.
Objective The My Baby’s Movements (MBM) trial aimed to evaluate the impact on stillbirth rates of a multifaceted awareness package (MBM intervention). Design Stepped-wedge cluster-randomised controlled trial. Setting Twenty-seven maternity hospitals in Australia and New Zealand. Population Women with a singleton pregnancy without major fetal anomaly ≥28 weeks’ gestation from August 2016-May 2019. Methods The MBM intervention was implemented at randomly assigned time points with sequential introduction into 8 clusters of 3-5 hospitals at four-monthly intervals. The stillbirth rate was compared in the control and intervention periods. Generalised linear mixed models controlled for calendar time, clustering, and hospital effects. Outcome Measures Stillbirth at ≥28 weeks’ gestation. Results There were 304,853 births with 290,219 meeting inclusion criteria: 150,079 in control and 140,140 in intervention periods. The stillbirth rate during the intervention was lower than the control period (2.2/1000 births versus 2.4, odds ratio [OR] 0.91, 95% Confidence Intervals [CI] 0.78-1.06, p=0.22). The decrease was larger across calendar time with 2.7/1000 in the first 18 months versus 2.0/1000 in the last 18 months (OR 0.74; 95% CI 0.63-0.86; p≤0.01). Following adjustment, stillbirth rates between the control and intervention periods were not significantly different: (aOR 1.18, 95% CI 0.93-1.50; p=0.18). No increase in secondary outcomes, including obstetric intervention or adverse neonatal outcome, was evident. Conclusion The MBM intervention did not reduce stillbirths beyond the downward trend over time, suggesting hospitals may have implemented best practice in DFM management outside their randomisation schedule. The role of interventions for raising awareness of DFM remains unclear
AIMS:The bidirectional association between diabetes mellitus (DM) and pancreatic cancer (PC) is established; however, the strength of association between duration of DM and risk of PC needs further investigation.METHODS:We conducted a case-control study nested within a population-based cohort of Australian women established using record linkage. Women diagnosed with PC from July 2007 to December 2013, were matched to five controls based on age and state of residence. DM was defined according to prescription of anti-diabetic medication from administrative prescription data. We used conditional logistic regression to calculate odds ratios (OR) and 95% confidence intervals (CI), adjusted for area-level socioeconomic status, rurality of residence, weighted comorbidity score, and predicted probability of obesity.RESULTS:The analyses included 7,267 cases and 35,978 controls. The mean age at the time of DM diagnosis was 71 years whereas the mean age at the time of diagnosis of PC was 76 years. A history of DM of any duration was associated with a 2-fold increase in risk of PC (OR=2.12; 95%CI:1.96-2.29) compared to having no history of DM. The risk decreased with increasing duration of DM. The highest risk was in those who had recent-onset DM (OR=8.08; 95%CI:6.88-9.50 for <12 months of DM), but the risk remained elevated with ≥5 years of DM (OR=1.40; 95%CI:1.27-1.55).CONCLUSION:The markedly increased risk of PC in those with recent-onset DM emphasises the need for further research to distinguish patients for whom new-onset DM is a manifestation of PC from those with type-2 DM. The elevated risk associated with long-standing DM suggests that preventing DM may contribute to a reduction in the incidence of PC.
Stillbirth is a major public health problem that is slow to improve in Australia. Understanding the causes of stillbirth through appropriate investigation is the cornerstone of prevention and important for parents to understand why their baby died.
Purpose: While central nervous system (CNS) tumors account for only 10% of adolescent and young adult (AYA) cancers, they are the leading cause of cancer death in this age group. Using national data for Australia, we describe the presentation, treatment, and survival for AYAs diagnosed with CNS tumors. Methods: A population-based study of 15-24 year-olds diagnosed with CNS tumors (low- and high-grade glioma [LGG, HGG], medulloblastoma [MB], primitive neuroectodermal tumors [PNET], ependymoma [EP]) or other (e.g., low-grade neuronal tumor) between 2007 and 2012. Clinical details were extracted from hospital medical records for each patient. Treatment centers were classified as pediatric or adult services. Results: Two hundred seventy-five patients (129 LGG, 77 HGG, 23 MB, 10 PNET, 19 EP, 17 other) were identified, with 17% treated at pediatric hospitals. Symptoms (headache [53%], nausea [31%]) were present for a median of 3 weeks before consulting a health professional. Of LGG patients, 15% had radiotherapy (RT) and 12% chemotherapy (CT). Of HGG patients, 81% had RT and 75% CT. All MB and PNET were managed with surgery, and 74% of MB and 80% of PNET had both RT and CT. Treatment did not differ by treatment center type. Five-year survival for LGG and EP was over 80%, but was 42% for HGG and 20% for PNET. Conclusions: This national, population-based study indicates similar treatment for AYA patients with CNS tumors between pediatric and adult services. Poor outcomes for HGG and PNET patients highlight the need for clinical trials of novel approaches for these tumors.
(Abstracted from JAMA Network Open 2021;4(4):e215071) Decreased fetal movement (DFM) has previously been associated with stillbirth and other adverse perinatal outcomes. Several guidelines highlight the importance of DFM as a sign associated with a risk of stillbirth; however, there is limited national guidance to incorporate this monitoring into stillbirth reduction strategies.
Stillbirth is a major public health problem with an enormous mortality burden and psychosocial impact on parents, families and the wider community both globally and in Australia. In 2015, Australia’s late gestation stillbirth rate was over 30% higher than that of the best-performing countries globally, highlighting the urgent need for action. We present an overview of the foundations which led to the establishment of Australia’s NHMRC Centre of Research Excellence in Stillbirth (Stillbirth CRE) in 2017 and highlight key activities in the following areas: Opportunities to expand and improve collaborations between research teams; Supporting the conduct and development of innovative, high quality, collaborative research that incorporates a strong parent voice; Promoting effective translation of research into health policy and/or practice; and the Regional and global work of the Stillbirth CRE. We highlight the first-ever Senate Inquiry into Stillbirth in Australia in 2018. These events ultimately led to the development of a National Stillbirth Action and Implementation Plan for Australia with the aims of reducing stillbirth rates by 20% over the next five years, reducing the disparity in stillbirth rates between advantaged and disadvantaged communities, and improving care for all families who experience this loss.
Background In 2015, the stillbirth rate after 28 weeks (late gestation) in Australia was 35% higher than countries with the lowest rates globally. Reductions in late gestation stillbirth rates have steadily improved in Australia. However, to amplify and sustain reductions, more needs to be done to reduce practice variation and address sub-optimal care. Implementing bundles for maternity care improvement in the UK have been associated with a 20% reduction in stillbirth rates. A similar approach is underway in Australia; the Safer Baby Bundle (SBB) with five elements: 1) supporting women to stop smoking in pregnancy, 2) improving detection and management of fetal growth restriction, 3) raising awareness and improving care for women with decreased fetal movements, 4) improving awareness of maternal safe going-to-sleep position in late pregnancy, 5) improving decision making about the timing of birth for women with risk factors for stillbirth. Methods This is a mixed-methods study of maternity services across three Australian states; Queensland, Victoria and New South Wales. The study includes evaluation of ‘targeted’ implementer sites (combined total approximately 113,000 births annually, 50% of births in these states) and monitoring of key outcomes state-wide across all maternity services. Progressive implementation over 2.5 years, managed by state Departments of Health, commenced from mid-2019. This study will determine the impact of implementing the SBB on maternity services and perinatal outcomes, specifically for reducing late gestation stillbirth. Comprehensive process, impact, and outcome evaluations will be conducted using routinely collected perinatal data, pre- and post- implementation surveys, clinical audits, focus group discussions and interviews. Evaluations explore the views and experiences of clinicians embedding the SBB into routine practice as well as women’s experience with care and the acceptability of the initiative. Discussion This protocol describes the evaluation of the SBB initiative and will provide evidence for the value of a systematic, but pragmatic, approach to strategies to reduce the evidence-practice gaps across maternity services. We hypothesise successful implementation and uptake across three Australian states (amplified nationally) will be effective in reducing late gestation stillbirths to that of the best performing countries globally, equating to at least 150 lives saved annually. Trial registration The Safer Baby Bundle Study was retrospectively registered on the ACTRN12619001777189 database, date assigned 16/12/2019
Background: While overall survival (OS) for cancer in adolescents and young adults (AYA) has improved, there has been little change in AYA survival for several types of sarcomas. Using national data for Australia we describe (1) the treatment centers caring for AYA sarcoma, (2) treatments provided, and (3) survival outcomes. Procedure: National population-based study assessing treatment of 15-24 year-olds diagnosed with soft tissue sarcoma (STS), bone sarcoma (BS), and Ewing family tumors (ET) between 2007 and 2012. Treatment details were abstracted from hospital medical records. Treatment centers were classified as pediatric or adult specialist AYA/sarcoma center, or other adult. Cox proportional hazard regression analyses examined associations between type of treatment center and OS. Results: Sixty-one hospitals delivered treatment to 318 patients (135 STS; 91 BS, 92 ET), with 9%, 22%, and 17% of STS, BS, and ET, respectively, treated at pediatric and 62%, 59%, and 71% at adult specialist hospitals. Of 18-24 year-olds, 82% of BS, 90% of ET, and 73% of rhabdomyosarcomas at adult specialist centers were on a trial or standard protocol, compared with 42%, 89%, and 100%, respectively, at nonspecialist adult hospitals. After adjusting for disease and patient characteristics, survival was not associated with treatment center type for any disease type. However, ET survival was poorer for patients not receiving a standard chemotherapy protocol. Conclusions: Around 10% of AYA sarcoma patients attending adult hospitals were not on a standard protocol. Poorer survival for ET patients not on a standard protocol highlights the importance of ensuring all patients receive optimal care.
Background Stillbirth is a devastating pregnancy outcome that has a profound and lasting impact on women and families. Globally, there are over 2.6 million stillbirths annually and progress in reducing these deaths has been slow. Maternal perception of decreased fetal movements (DFM) is strongly associated with stillbirth. However, maternal awareness of DFM and clinical management of women reporting DFM is often suboptimal. The My Baby’s Movements trial aims to evaluate an intervention package for maternity services including a mobile phone application for women and clinician education (MBM intervention) in reducing late gestation stillbirth rates. Methods/design This is a stepped wedge cluster randomised controlled trial with sequential introduction of the MBM intervention to 8 groups of 3–5 hospitals at four-monthly intervals over 3 years. The target population is women with a singleton pregnancy, without lethal fetal abnormality, attending for antenatal care and clinicians providing maternity care at 26 maternity services in Australia and New Zealand. The primary outcome is stillbirth from 28 weeks’ gestation. Secondary outcomes address: a) neonatal morbidity and mortality; b) maternal psychosocial outcomes and health-seeking behaviour; c) health services utilisation; d) women’s and clinicians’ knowledge of fetal movements; and e) cost. 256,700 births (average of 3170 per hospital) will detect a 30% reduction in stillbirth rates from 3/1000 births to 2/1000 births, assuming a significance level of 5%. Analysis will utilise generalised linear mixed models. Discussion Maternal perception of DFM is a marker of an at-risk pregnancy and commonly precedes a stillbirth. MBM offers a simple, inexpensive resource to reduce the number of stillborn babies, and families suffering the distressing consequences of such a loss. This large pragmatic trial will provide evidence on benefits and potential harms of raising awareness of DFM using a mobile phone app. Trial registration ACTRN12614000291684 .

PurposeUptake of biosimilars depends on clinicians and patients having confidence in the evidential basis of marketing approval. The aim of this systematic review was to assess the evidential role of randomised clinical endpoint studies in the marketing approval of trastuzumab biosimilars.MethodsWe searched PubMed for any published reports of randomised studies associated with the five trastuzumab biosimilars approved by the EMA, as on 31 January 2019. We also searched ClinicalTrials.gov for any ongoing studies for other trastuzumab biosimilars.ResultsWe identified eight published papers or abstracts for seven randomised clinical endpoint studies for five trastuzumab biosimilars approved by the EMA: four studies in the neoadjuvant setting and three in the first-line metastatic setting. Another six unpublished or ongoing studies for other trastuzumab biosimilars were identified via ClinicalTrials.gov. According to GRADE, and considered in isolation, the randomised studies would be categorised as low-quality evidence because of the use of surrogate endpoints and the small sample size. However, according to GRADE, the totality-of-evidence for each of the five approved trastuzumab biosimilars would be categorised as high quality in that further data would be unlikely to change the conclusion that each biosimilar was not different from Herceptin in any clinically important way.ConclusionThe pivotal data for eachmarketing approval was not the randomised clinical endpoint study, but the in vitro analytic characterisation. Regulatory confidence in in vitro analytic characterisation stems from years of experience with manufacturing changes for originator biological medicines. This emphasis on in vitro data, as the most sensitive way to detect clinically important differences, will be a new way of thinking for many oncologists.
The prevalence of stillbirth in many high income countries like Australia has remained unchanged for over 30 years. The 2018 Australian government Senate Select Committee on Stillbirth Research and Education highlighted the need for a public health campaign to encourage public conversations and increase awareness. However, there is little evidence about the community’s knowledge and perceptions towards pregnancy and stillbirth, nor their aspirations for a public health campaign.To assess the general knowledge, perceptions, myths and attitudes towards stillbirth to inform future public health campaigns.Australian participants (n = 344; predominately women n = 294 (85.5%)) were recruited via Facebook.com. They completed a cross-sectional online survey designed to assess their knowledge of pregnancy and stillbirth, with additional questions on socio-demographic characteristics.Stillbirth knowledge and awareness of incidence was low in this sample. Prominent myths, such as baby runs out of room in the uterus (n = 112, 33%) and baby slows down when preparing for labour (n = 24, 27%) were endorsed. Only 25% (n = 85) knew the prevalence of stillbirth in Australia (six per day). Almost two-thirds (n = 205; 62%) agreed that there needs to be a public health campaign, however one in five (n = 65; 20%) were concerned that talking about stillbirth with pregnant women may cause them to worry.Our findings reinforce the need for a targeted campaign, which educates the general population about the definition and prevalence of stillbirth, stillbirth risks and modifiable health behaviours. Appropriate messaging should target pregnant women during antenatal care as well as their support and care systems (family, friends, and care providers).
Purpose: This study investigated the impact of fertility-related discussions on Adolescent and Young Adult (AYA) cancer patients' quality of life (QoL) and the factors influencing provision of these discussions.Methods: Recruitment was conducted through population-based state cancer registries. Eligible AYAs were 15-24years at diagnosis, 3-24months postdiagnosis, with any cancer (except early stage melanoma). As part of a larger survey, AYAs were asked about their experiences of fertility-related discussions and QoL (FACT-G).Results: Of the 207 AYAs returning surveys (29% response rate) 88% reported a discussion about infertility risks, 75% reported a discussion about preservation options and 59% were offered a referral to a fertility specialist. Patients attending health services with an AYA focus were more likely than those attending other types of centers to report discussions of fertility preservation (FP) options (85% versus 67%) and referrals (75% versus 49%). Social well-being was positively related to discussions about preservation options and being provided fertility risk information in a sensitive, supportive manner.Conclusions: Providing a sensitive and proactive discussion about fertility-related risks may benefit AYAs' well-being. Services with an AYA focus are fulfilling their mandate of ensuring optimal fertility-related care for AYA cancer patients.
