There are structural and functional modifications that occur to the neonatal heart immediately after birth. While a number of studies recently have assessed cardiac function in the newborn, there is a dearth of data on diastolic function in the neonatal period during transition and into infancy. The objective of this study is to assess diastolic function in a large cohort of infants to provide normative reference values and to assess the influence of predefined maternal and infant characteristics.

This is a single-centre observational study of babies born at 35 weeks of gestation and above, involving echocardiography in the first 2 DOL and longitudinal follow-up of these infants up to 18 months of age. The echocardiographic measurements to assess diastolic function used in this study include conventional echo measures, novel echo measures using tissue Doppler imaging and deformation measures using 2D speckle tracking echocardiography.

The protocol was approved by the Clinical Research Ethics Committee of the Cork Teaching Hospitals. The findings from this study will be disseminated in peer-reviewed journals and during scientific conferences.

Selection of antiseizure medications (ASMs) for newly diagnosed epilepsy remains largely a trial-and-error process. We have developed a machine learning (ML) model using retrospective data collected from five international cohorts that predicts response to different ASMs as the initial treatment for individual adults with new-onset epilepsy. This study aims to prospectively evaluate this model in Australia using a randomised controlled trial design.

At least 234 adult patients with newly diagnosed epilepsy will be recruited from 14 centres in Australia. Patients will be randomised 1:1 to the ML group or usual care group. The ML group will receive the ASM recommended by the model unless it is considered contraindicated by the neurologist. The usual care group will receive the ASM selected by the neurologist alone. Both the patient and neurologists conducting the follow-up will be blinded to the group assignment. Both groups will be followed up for 52 weeks to assess treatment outcomes. Additional information on adverse events, quality of life, mood and use of healthcare services and productivity will be collected using validated questionnaires. Acceptability of the model will also be assessed.

The primary outcome will be the proportion of participants who achieve seizure-freedom (defined as no seizures during the 12-month follow-up period) while taking the initially prescribed ASM. Secondary outcomes include time to treatment failure, time to first seizure after randomisation, changes in mood assessment score and quality of life score, direct healthcare costs, and loss of productivity during the treatment period.

This trial will provide class I evidence for the effectiveness of a ML model as a decision support tool for neurologists to select the first ASM for adults with newly diagnosed epilepsy.

This study is approved by the Alfred Health Human Research Ethics Committee (Project 130/23). Findings will be presented in academic conferences and submitted to peer-reviewed journals for publication.
