The Australian Paediatric Surveillance Unit (APSU), established in 1993 to address the paucity of national data on rare childhood disorders, has become an invaluable research resource. It facilitates prospective, active surveillance for a variety of rare disorders, with monthly reporting by ~1500 paediatricians, who are invited to notify incident cases and provide demographic and clinical data. APSU is highly collaborative (used by >400 individuals/organisations), patient-informed and productive (>300 publications). In 30 years, 72 studies have been initiated on rare infections, and genetic, psychological and neurological disorders, and injuries. Return rates of monthly report cards were >90% for 30 years and paediatricians have provided data for >90% of notified cases. Although there are limitations, including case underascertainment in remote regions, APSU often provides the only available national data. APSU has assisted the government in reporting to the WHO, developing national strategies, informing inquiries and investigating disease outbreaks. APSU data have informed paediatrician education, practice, policy, and service development and delivery. APSU was integral in establishing the International Network of Paediatric Surveillance Units (INoPSU) and supporting development of other units. APSU's expanded remit includes one-off surveys, hospital audits, systematic reviews, studies on the impacts of rare disorders on families, surveillance evaluations, and joint studies with INoPSU members. Paediatricians value the APSU, reporting that APSU data inform their practice. They must be congratulated for an outstanding collective commitment to the APSU, in providing unique data that contribute to our understanding of rare disorders and support optimal, evidence-based care and improved child health outcomes.

Oxytocin research is rapidly evolving and increasingly reveals that epigenetic modifications to the oxytocin receptor gene (OXTR) are functional, plastic, and reliable components of oxytocinergic system function. This review outlines how OXTR epigenetics are shaped by the early life environment, impact social-developmental outcomes, and have strong potential to serve as therapeutic targets. We first establish the malleability of OXTR epigenetics in infancy in both animal models and humans through research demonstrating the impact of the early life environment on OXTR DNA methylation (OXTRm) and subsequent social behavior. Next, we detail how OXTRm serves as a predictive mechanism for neurodevelopmental outcomes in animal models of social behavior such as the prairie vole, and summarize the role of OXTRm in psychiatric disorders, emotional processing, and attachment behavior in humans. We discuss the potential of further OXTRm research to improve oxytocin therapeutics by highlighting how a deeper knowledge of OXTRm could improve the therapeutic potential of exogenous oxytocin, how OXTRm may impact additional cellular mechanisms with therapeutic potential including control of the perinatal GABA switch, and how early life therapies may target the tuning of endogenous OXTRm. Finally, we review limitations of previous oxytocin research and make recommendations for future research. IMPACT: Previous research into oxytocin therapeutics has been hampered by methodological difficulties that may be improved by assay of the oxytocin receptor gene (OXTR) and its methylation (OXTRm) Key sites of OXTRm modification link early life exposures to developmental and behavioral outcomes OXTRm appears to have a critical period of development in early life Epigenetic modification of the oxytocin receptor gene could serve as a powerful target for therapeutic interventions.

CONCLUSIONS: This expert consensus provides a comprehensive guidance and a reference for the diagnosis and treatment of pertussis in children.

Evidence-based medicine (EBM) is the established, albeit at times conceptual, standard of care, and understanding its ongoing operational evolution is critical to JAACAP readers. At the center of operationalizing the concept of EBM are the accurate tools for screening, diagnosis, and outcome measurement. Historically, these instruments relied on trained raters assessing the patient's signs and symptoms.

CONCLUSIONS: Reductions in the use of medications for bronchiolitis achieved in 2019 through the implementation of our integrated clinical pathway have been sustained over the three subsequent waves.

CONCLUSIONS: Provider-facing interventions alone were not effective at increasing vaccine screening and administration in our PUC, but marked improvement was observed with the addition of a DNV. Future interventions are needed to address disparities. Additional investigation is needed to determine whether our results are reproducible in other PUCs with access to vaccines.

Numerous studies have attempted to identify potential biomarkers for early detection of bronchopulmonary dysplasia (BPD) in preterm infants using metabolomics techniques. However, the presence of consistent evidence remains elusive. Our study aimed to conduct a systematic review and meta-analysis to identify differences in small-molecule metabolites between BPD and non-BPD preterm infants. Through meticulous screening of numerous samples, we identified promising candidates, providing valuable insights for future research. We searched PubMed, the Cochrane Library, Embase, Web of Science, China National Knowledge Internet, Wan-fang database, Chinese Science and Technique Journal Database and Chinese Biomedical Literature Database from inception until January 16, 2024. Studies were comprehensively reviewed against inclusion criteria. We included case-control studies and adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Study quality was assessed with the Newcastle-Ottawa scale. We compared the changes in metabolite levels between the BPD and non-BPD preterm infants. A meta-analysis was conducted on targeted metabolomics research data based on the strategy of standardized mean differences (MD) and 95% confidence intervals (CI).Fifteen studies (1357 participants) were included. These clinical-based metabolomics studies clarified 110 differential metabolites between BPD and non-BPD preterm infants. The meta-analysis revealed higher glutamate concentration in the BPD group compared to the non-BPD group (MD = 1, 95% CI 0.59 to 1.41, p < 0.00001). Amino acids were identified as the key metabolites distinguishing preterm infants with and without BPD, with glutamate potentially serving as a BPD predictor in this population.

In perinatal medicine, the number of babies with life-limiting or life-threatening conditions is increasing and the benefits of providing palliative care with a holistic, interdisciplinary approach are well documented. It can be particularly challenging, however, to integrate palliative care into routine care where there exists uncertainty about a baby's diagnosis or potential outcome.This framework, developed collaboratively by the British Association of Perinatal Medicine (BAPM) and the Association of Paediatric Palliative Medicine (APPM), offers supportive guidance for all healthcare professionals working in perinatal medicine across antenatal and neonatal services. It explicitly acknowledges that palliative care is not just for babies who are dying or who will certainly die in early life; incorporating a palliative approach into antenatal and neonatal care for all babies with an uncertain outcome can be particularly valuable. The framework provides guidance on recognising babies who may benefit from palliative care and outlines the key elements of perinatal palliative care: holistic family support, empowering parents to be parents, parallel planning, symptom management and loss and bereavement care. It provides recommendations for the delivery of palliative care services, advocating for a unified approach that involves all members of the perinatal team, supported by specialist services as needed.This framework calls for a shift in the philosophy and practice of perinatal care to integrate palliative care into the everyday and to recognise and embrace the challenge of uncertain prognosis.

BACKGROUND: Limited data exist on population-level mortality outcomes related to extreme neonatal hyperbilirubinemia (EHB) and this study examines trends in annual infant mortality rate (IMR) attributed to hemolytic and perinatal jaundice among Germany, France, Italy, Portugal, Greece and Spain from 1990 to 2019.

The rapid and accurate diagnosis of rare diseases is paramount in directing clinical management. In recent years, the integration of multi-omics approaches has emerged as a potential strategy to overcome diagnostic hurdles. This review examines the application of multi-omics technologies, including genomics, epigenomics, transcriptomics, proteomics, and metabolomics, in relation to the diagnostic journey of rare diseases. We explore how these combined approaches enhance the detection of pathogenic genetic variants and decipher molecular mechanisms. This review highlights the groundbreaking potential of multi-omics in advancing the precision medicine paradigm for rare diseases, offering insights into future directions and clinical applications. IMPACT: This review discusses using current tests and emerging technologies to diagnose pediatric rare diseases. We describe the next steps after inconclusive molecular testing and a structure for using multi-omics in further investigations. The use of multi-omics is expanding, and it is essential to incorporate it into clinical practice to enhance individualized patient care.
