Motivation Human Phenotype Ontology (HPO)-based phenotype concept recognition (CR) underpins a faster and more effective mechanism to create patient phenotype profiles or to document novel phenotype-centred knowledge statements. While the increasing adoption of large language models (LLMs) for natural language understanding has led to several LLM-based solutions, we argue that their intrinsic resource-intensive nature is not suitable for realistic management of the phenotype CR lifecycle. Consequently, we propose to go back to the basics and adopt a dictionary-based approach that enables both an immediate refresh of the ontological concepts as well as efficient re-analysis of past data. Results We developed a dictionary-based approach using a pre-built large collection of clusters of morphologically equivalent tokens—to address lexical variability and a more effective CR step by reducing the entity boundary detection strictly to candidates consisting of tokens belonging to ontology concepts. Our method achieves state-of-the-art results (0.76 F1 on the GSC+ corpus) and a processing efficiency of 10 000 publication abstracts in 5 s. Availability and implementation FastHPOCR is available as a Python package installable via pip. The source code is available at https://github.com/tudorgroza/fast%5fhpo%5fcr.

- Abstract
Purpose: Medications are commonly used during pregnancy to manage pre‐existing conditions and conditions that arise during pregnancy. However, not all medications are safe to use in pregnancy. This study utilized privacy‐preserving record linkage (PPRL) to examine medications dispensed under the national Pharmaceutical Benefits Scheme (PBS) to pregnant women in Western Australia (WA) overall and by medication safety category. Methods: In this retrospective, cross‐sectional, population‐based study, state perinatal records (Midwives Notification Scheme) were linked with national PBS dispensing data using PPRL. Live and stillborn neonates born between 2012 and 2019 in WA were included. The proportion of pregnancies during which the mother was dispensed a PBS medication was calculated, overall and by medication safety category. Factors associated with PBS medication dispensing were examined using logistic regression. Results: PPRL linkage identified matching records for 97.4% of women with perinatal records. A total of 271 739 pregnancies were identified, with 158 585 (58.4%) pregnancies involving the dispensing of at least one PBS medication. Category A medications (those considered safe in pregnancy) were the most commonly dispensed (n = 119 126, 43.8%) followed by B3 (n = 51 135, 18.8%) and B1 (n = 42 388, 15.6%) medication (those with unknown safety). Over the study period, the dispensing of PBS medications in pregnancy increased (OR: 1.06, 95%CI: 1.06, 1.07). The strongest predictor of medication dispensing in pregnancy was pre‐pregnancy dispensing (OR: 3.61, 95%CI: 3.54, 3.68). Other factors associated with medication use in pregnancy were smoking, older maternal age, obesity, and prior pregnancies. Conclusion: Privacy preserving record linkage provides a way to link cross‐jurisdictional data while preserving patient confidentiality and data security. The dispensing of PBS medication in pregnancy was common and increased over time, with approximately 60% of women dispensed at least one medication during pregnancy. [ABSTRACT FROM AUTHOR]

Comprehensive CA-CP Study Group: Ingeborg Barisic, Vlatka Bosnjak Mejaski, Emmanuelle Amar, Elodie Sellier, Sandra Julsen Hollung, Kari Klungsøyr, Paula Braz, Daniel Virella, Catherine Gibson, Karin Källén, Susan M Reid, Gareth Baynam, Dylan Gration, Michèle Hansen, Linda Watson Comprehensive CA-CP Study Group: Paula Braz, Daniel Virella. INSA, Portugal. Aim: To describe the major congenital anomalies present in children with postneonatally acquired cerebral palsy (CP), and to compare clinical outcomes and cause of postneonatally acquired CP between children with and without anomalies. Method: Data were linked between total population CP and congenital anomaly registers in five European and three Australian regions for children born 1991 to 2009 (n=468 children with postneonatally acquired CP; 255 males, 213 females). Data were pooled and children classified into mutually exclusive categories based on type of congenital anomaly. The proportion of children with congenital anomalies was calculated. Clinical outcomes and cause of postneonatally acquired CP were compared between children with and without anomalies. Results: Major congenital anomalies were reported in 25.6% (95% confidence interval [CI] 21.7-29.9) of children with postneonatally acquired CP. Cardiac anomalies, often severe, were common and present in 14.5% of children with postneonatally acquired CP. Clinical outcomes were not more severe in children with congenital anomalies than those without anomalies. Cause of postneonatally acquired CP differed with the presence of congenital anomalies, with cerebrovascular accidents predominating in the anomaly group. Congenital anomalies were likely associated with cause of postneonatally acquired CP in 77% of children with anomalies. Interpretation: In this large, international study of children with postneonatally acquired CP, congenital anomalies (particularly cardiac anomalies) were common. Future research should determine specific causal pathways to postneonatally acquired CP that include congenital anomalies to identify opportunities for prevention. What this paper adds: One-quarter of children with postneonatally acquired cerebral palsy (CP) have a major congenital anomaly. Cardiac anomalies, often severe, are the most common anomalies. Causes of postneonatally acquired CP differ between children with and without congenital anomalies. Objetivo: Describir las principales anomalías congenitas presentes en niños con parálisis cerebral (PC) adquirida posnatalmente y comparar los resultados clínicos y la causa de PC entre niños con y sin anomalías. Método: Se relacionaron los registros de datos de la población con PC y los registros de anomalías congenitas de cinco regiones de Europa y tres de Australia de niños nacidos de 1991 a 2009 (n = 468 niños con PC adquirida posnatalmente; 255 varones, 213 mujeres). Se agruparon los datos y clasificaron en categor ıas mutuamente excluyentes segun el tipo de anomalías congenita. Se calcul o la pro-porcion de ni nos con anomalías congenitas. Se compararon los resultados clínicos y la causa de la PC adquirida posnatalmente entre niños con y sin anomalías. Resultados: Se registraron anomalías congenitas importantes en el 25,6% (intervalo de confianza [IC] del 95%: 21,7-29,9) de los niños con PC adquirida despues del nacimiento. Hubo una alta frecuencia de anomalías cardíacas, que estaban presentes en el 14,5% de los niños con PC adquirida posnatalmente. La evolución clínica no fue diferentes entre niños con o sin anomalías congenitas. La causa de PC adquirida posnatalmente vario con la presencia de anomalías congenitas, predominando los accidentes cerebrovasculares en el grupo de anomalías congenitas. La causa de PC adquirida posnatalmente esta probablemente asociada con anomalias congenitas en el 77% de los niños con anomalías. Interpretacion: En este estudio internacional de niños con PC adquirida posnatalmente, las anomalías congenitas fueron frecuentes, particularmente las anomalías cardíacas. Las investigaciones futuras deben determinar las vías causales específicas de la PC adquirida posnatalmente que incluyen anomalías congenitas para identificar oportunidades de prevención. info:eu-repo/semantics/publishedVersion

The clinical utility of computational phenotyping for both genetic and rare diseases is increasingly appreciated; however, its true potential is yet to be fully realized. Alongside the growing clinical and research availability of sequencing technologies, precise deep and scalable phenotyping is required to serve unmet need in genetic and rare diseases. To improve the lives of individuals affected with rare diseases through deep phenotyping, global big data interrogation is necessary to aid our understanding of disease biology, assist diagnosis, and develop targeted treatment strategies. This includes the application of cutting-edge machine learning methods to image data. As with most digital tools employed in health care, there are ethical and data governance challenges associated with using identifiable personal image data. There are also risks with failing to deliver on the patient benefits of these new technologies, the biggest of which is posed by data siloing. The Minerva Initiative has been designed to enable the public good of deep phenotyping while mitigating these ethical risks. Its open structure, enabling collaboration and data sharing between individuals, clinicians, researchers and private enterprise, is key for delivering precision public health. [ABSTRACT FROM AUTHOR]

- Abstract
Silver‐Russell syndrome (SRS OMIM 180860) is a rare, albeit well‐recognized disorder characterized by severe intrauterine and postnatal growth retardation. It remains a clinical diagnosis with a molecular cause identifiable in approximately 60%–70% of patients. We report a 4‐year‐old Australian Aboriginal girl who was born at 32 weeks gestation with features strongly suggestive of SRS, after extensive investigation she was referred to our undiagnosed disease program (UDP). Genomic sequencing was performed which identified a heterozygous splice site variant in IGF2 which is predicted to be pathogenic by in‐silico studies, paternal allelic origin, de novo status, and RNA studies on fibroblasts. We compare clinical findings with reported patients to add to the knowledge base on IGF2 variants and to promote the engagement of other Australian Aboriginal families in genomic medicine.

- Abstract
The diagnostic odyssey for people living with rare diseases (PLWRD) is often prolonged for myriad reasons including an initial failure to consider rare disease and challenges to systemically and systematically identifying and tracking undiagnosed diseases across the diagnostic journey. This often results in isolation, uncertainty, a delay to targeted treatments and increase in risk of complications with significant consequences for patient and family wellbeing. This article aims to highlight key time points to consider a rare disease diagnosis along with elements to consider in the potential operational classification for undiagnosed rare diseases during the diagnostic odyssey. We discuss the need to create a coding framework that traverses all stages of the diagnostic odyssey for PLWRD along with the potential benefits this will have to PLWRD and the wider community., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Baxter, Hansen, Gration, Groza and Baynam.)
