Kawasaki disease is a paediatric vasculitis that presents with fever, rash, conjunctivitis, mucositis, lymphadenopathy, and extremity changes, and primarily affects children younger than 5 years. Coronary artery aneurysms are observed in approximately 20% of patients without treatment. Giant coronary artery aneurysms are rare but can result in substantial morbidity and mortality due to the risk of thrombosis, stenosis, and myocardial infarction. Infants younger than 6 months and children with coronary artery abnormalities are at highest risk for the development of large or giant coronary artery aneurysms, necessitating swift identification and aggressive treatment. The children at high risk for coronary artery aneurysms warrant primary intensification therapy; however, what the most optimal adjunct therapy might be to reduce their risk is unclear and large-scale international trials are needed. Kawasaki disease is a clinical diagnosis that shares many features with other common febrile illnesses, including multisystem inflammatory syndrome in children. Identifying biomarkers that can distinguish Kawasaki disease from similar conditions and predict coronary artery aneurysm risk are needed to aid timely diagnosis, guide management, and improve patient outcomes.

<div><h3>Background</h3><p>Childhood-onset systemic lupus erythematosus (SLE) is a complex autoimmune disorder that can lead to serious organ damage. Despite the prevalence of SLE among children in Asian countries, treatment guidelines, prognosis, and clinical decision making for children with SLE are limited by gaps in region-specific epidemiological data. The aim of this study was to analyse epidemiological characteristics of childhood-onset SLE and associated organ involvement and in-hospital mortality in China.</p></div><div><h3>Methods</h3><p>In this nationwide study, we searched standardised hospital discharge records submitted to the Hospital Quality Monitoring System (HQMS) between Jan 1, 2016, and Dec 31, 2021, for patients with a diagnosis of childhood-onset SLE based on the 2019 American College of Rheumatology or 2012 Systemic Lupus International Collaborating Clinics classification criteria. We selected records for patients aged 18 years and younger containing relevant ICD 10th revision diagnostic codes (specifically M32) among discharge diagnostic codes. We excluded records for patients younger than 5 years, whose SLE diagnosis was presumed to be monogenic lupus, and for patients with overlap syndromes or unidentified sex. Date of diagnosis (equal to the first hospital discharge date), age, organ involvement, intensive care unit (ICU) treatment, and in-hospital mortality were extracted from the records. Incidence rates for 2017, 2018, 2019, 2020, and 2021 were identified with five washout periods ranging from 12 months (Jan 1–Dec 31, 2016) to 60 months (Jan 1, 2016–Dec 31, 2020). Data were stratified by sex, age relative to puberty onset, organ involvement and concurrent infection at time of diagnosis, human development index of region of residence, hospital level, and hospital type. Incidence trends by sex, age relative to puberty onset, and year were derived by joinpoint regression analysis, with 95% CIs calculated by the Poisson exact method. Major organ involvement was assessed according to definitions in the British Isles Lupus Assessment Group 2004 disease activity index. Outcomes of ICU admission after first diagnosis and in-hospital death after ICU admission were analysed in Cox proportional hazards models, with p values and 95% CIs calculated with the parametric method.</p></div><div><h3>Findings</h3><p>Between Jan 1, 2016, and Dec 31, 2021, the HQMS received 134 956 hospital discharge records containing the M32 discharge diagnostic code for patients aged 18 years or younger. 6286 records were excluded, leaving 128 670 records representing 54 338 patients aged 5–18 years; of these, 43 756 patients (36 153 girls and 7603 boys) received their childhood-onset SLE diagnosis on or after Jan 1, 2017. Between Jan 1, 2017, and Dec 31, 2021, the SLE incidence rate was 3·97 (95% CI 3·93–4·01) per 100 000 person-years, with a declining trend during the 5-year period.

Extracorporeal membrane oxygenation (ECMO) is a high-risk and low-volume life support with increasing clinical study. However, heterogenous outcome definitions impede data assimilation into evidence to guide practice. The Academic Research Consortium (ARC), an international collaborative forum committed to facilitating the creation of stakeholder-driven consensus nomenclature and outcomes for clinical trials of medical devices, supported the ECMO Core Elements Needed for Trials Regulation And quality of Life (ECMO-CENTRAL) ARC. The ECMO-CENTRAL ARC was assembled to develop definitions of paediatric ECMO adverse events for use in clinical trials and regulatory device evaluation. An initial candidate list of ECMO adverse events derived from the mechanical circulatory support ARC was supplemented with a review of ECMO-relevant adverse event definitions collated from literature published between Jan 1, 1988, and Feb 20, 2023. Distinct teams of international topic experts drafted separate adverse event definitions that were harmonised to existing literature when appropriate. Draft definitions were revised for paediatric ECMO relevance with input from patients, families, and an international expert panel of trialists, clinicians, statisticians, biomedical engineers, device developers, and regulatory agencies. ECMO-CENTRAL ARC was revised and disseminated across research societies and professional organisations. Up to three rounds of internet-based anonymous surveys were planned as a modified Delphi process. The expert panel defined 13 adverse event definitions: neurological, bleeding, device malfunction, acute kidney injury, haemolysis, infection, vascular access-associated injury, non-CNS thrombosis, hepatic dysfunction, right heart failure, left ventricular overload, lactic acidaemia, and hypoxaemia. Definitional structure varied. Among 165 expert panel members, 114 were eligible to vote and 111 voted. Consensus was achieved for all proposed definitions. Agreement ranged from 82% to 95%. ECMO-CENTRAL ARC paired rigorous development with methodical stakeholder involvement and dissemination to define paediatric ECMO adverse events. These definitions will facilitate new research and the assimilation of data across clinical trials and ECMO device evaluation in children.

Alcohol is a known teratogen and prenatal alcohol exposure remains a major ongoing public health concern. Fetal alcohol spectrum disorder has become the diagnosis for describing individuals who have been affected by prenatal alcohol exposure. In this Viewpoint, we raise major concerns about its continued use as a diagnostic term in how it perpetuates a misleading and outdated narrative about child development and maternal health. We argue that the term fetal alcohol spectrum disorder has contributed to a culture of racism and discrimination for many who are diagnosed with it. The term fetal alcohol spectrum disorder fails to capture the progress made in our collective understanding of neurodevelopment through advancements in the field of genetics and in understanding the effects of trauma and adversity. We call for urgent international collaborative action to review the use of it as a diagnostic term and, more broadly, to reconsider the practice of diagnosing disabilities as medical illnesses. We suggest that this practice fails to recognise that outcomes of functioning and participation in individuals are not only the results of health conditions, but are also the products of complex interactions and experiences of individuals within the families and societies in which they live.
