In-utero transfer, survival-focused care and survival to 28-days at 22-24 weeks' gestation pre- and post- implementation of an extreme prematurity management guideline in Victoria, Australia.

Background: Care for infants born at 22-24 weeks' gestation varies globally, with an increasing willingness to provide survival-focused ('active') care for infants born at 22 weeks' gestation in recent years. This study aims to report changes in care for infants born at 22-24 weeks before and after the introduction of a statewide guideline for extreme prematurity (EP).

Methods: A retrospective cohort study was conducted, including all live births at 22-24 weeks in tertiary perinatal centres from 1 January 2015 to 31 December 2022 in Victoria, Australia.

Associations between physical activity and development in preschool-aged children born <30 weeks' gestation: a cohort study.

Objective: To investigate the effect of physical activity (PA) on development (motor, cognitive, social-emotional) in children 4-5 years old born <30 weeks' gestation, and to describe subgroups of children at risk of low PA in this cohort.

Design: Longitudinal cohort study.

Patients: 123 children born <30 weeks were recruited at birth and assessed between 4 and 5 years' corrected age.

Neurosensory, cognitive and academic outcomes at 8 years in children born 22-23 weeks' gestation compared with more mature births.

Unlabelled: Despite providing intensive care to more infants born <24 weeks' gestation, data on school-age outcomes, critical for counselling and decision-making, are sparse.

Objective: To compare major neurosensory, cognitive and academic impairment among school-aged children born extremely preterm at 22-23 weeks' gestation (EP22-23) with those born 24-25 weeks (EP24-25), 26-27 weeks (EP26-27) and term (≥37 weeks).

Design: Three prospective longitudinal cohorts.

Quantifying Bone Strength Deficits in Young Adults Born Extremely Preterm or Extremely Low Birth Weight.

The long-term bone health of young adults born extremely preterm (EP; <28 weeks' gestation) or extremely low birth weight (ELBW; <1000 g birth weight) in the post-surfactant era (since the early 1990s) is unclear. This study investigated their bone structure and estimated bone strength using peripheral quantitative computed tomography (pQCT)-based finite element modeling (pQCT-FEM). Results using this technique have been associated with bone fragility in several clinical settings.

Long-lasting effects of very preterm birth on brain structure in adulthood: A systematic review and meta-analysis.

Early life experiences, such as very preterm (VP) birth, can affect brain and cognitive development. Several prior studies investigated brain structure in adults born VP; synthesising these studies may help to provide a clearer understanding of long-term effects of VP birth on the brain. We systematically searched Medline and Embase for articles that investigated brain structure using MRI in adulthood in individuals born VP (<32 weeks' gestation) or with very low birth weight (VLBW; <1500 g), and controls born at term or with normal birth weight.

Impact of current Australian paid parental leave on families of preterm and sick infants.

Aim: Parents of preterm or sick infants are at increased risk of mental health problems. The financial stress associated with an infant's prolonged hospital stay can have an additional negative effect on families' wellbeing and child development. This study explores parent use of Australian paid parental leave (PPL) and the financial impact of having an infant requiring neonatal care.

Brain tissue microstructural and free-water composition 13 years after very preterm birth.

There have been many studies demonstrating children born very preterm exhibit brain white matter microstructural alterations, which have been related to neurodevelopmental difficulties. These prior studies have often been based on diffusion MRI modelling and analysis techniques, which commonly focussed on white matter microstructural properties in children born very preterm. However, there have been relatively fewer studies investigating the free-water content of the white matter, and also the microstructure and free-water content of the cortical grey matter, in children born very preterm.

Investigating brain structural maturation in children and adolescents born very preterm using the brain age framework.

Very preterm (VP) birth is associated with an increased risk for later neurodevelopmental and behavioural challenges. Although the neurobiological underpinnings of such challenges continue to be explored, previous studies have reported brain volume and morphology alterations in children and adolescents born VP compared with full-term (FT)-born controls. How these alterations relate to the trajectory of brain maturation, with potential implications for later brain ageing, remains unclear.

Psychiatric disorders in individuals born very preterm / very low-birth weight: An individual participant data (IPD) meta-analysis.

Background: Data on psychiatric disorders in survivors born very preterm (VP; <32 weeks) or very low birthweight (VLBW; <1500 g) are sparse. We compared rates of psychiatric diagnoses between VP/VLBW and term-born, normal birthweight (term/NBW) control participants.

Methods: This individual participant data (IPD) meta-analysis pooled data from eligible groups in the Adults born Preterm International Collaboration (APIC).

Identifying research priorities in newborn medicine: a Delphi study of parents' views.

Objective: Neonatal conditions can have lifelong implications for the health and well-being of children and families. Traditionally, parents and patients have not been included in shaping the agenda for research and yet they are profoundly affected by the neonatal experience and its consequences. This study aimed to identify consensus research priorities among parents/patients of newborn medicine in Australia and New Zealand.

Wildfire smoke exposure and respiratory health outcomes in young adults born extremely preterm or extremely low birthweight.

Objective: Adults born either extremely preterm (EP, <28 weeks gestation) or extremely low birthweight (ELBW, <1000 g birthweight) have more obstructive airflow than controls of normal birthweight (>2499 g). We compared self-reported adverse respiratory health outcomes in young adults born EP/ELBW with controls following smoke exposure from the 2019/2020 wildfires in the Australian state of Victoria, and explored if any effects were mediated by airway obstruction, reflected in the forced expiratory volume in 1 second (FEV).

Methods: EP/ELBW participants were derived from all survivors born in the state of Victoria in 1991-92.

Parental mental health before and during pregnancy and offspring birth outcomes: A 20-year preconception cohort of maternal and paternal exposure.

Background: Preterm birth (PTB) and small for gestational age (SGA) are increasingly prevalent, with major consequences for health and development into later life. There is emerging evidence that some risk processes begin before pregnancy. We report on associations between maternal and paternal common mental disorders (CMD) before and during pregnancy and offspring PTB and SGA.

Long-term development of white matter fibre density and morphology up to 13 years after preterm birth: A fixel-based analysis.

Background: It is well documented that infants born very preterm (VP) are at risk of brain injury and altered brain development in the neonatal period, however there is a lack of long-term, longitudinal studies on the effects of VP birth on white matter development over childhood. Most previous studies were based on voxel-averaged, non-fibre-specific diffusion magnetic resonance imaging (MRI) measures, such as fractional anisotropy. In contrast, the novel diffusion MRI analysis framework, fixel-based analysis (FBA), enables whole-brain analysis of microstructural and macrostructural properties of individual fibre populations at a sub-voxel level.

Have outcomes following extremely preterm birth improved over time?

Increased survival of infants born preterm, especially those born extremely preterm (<28 weeks' gestation), has meant that more are reaching later childhood and adulthood. As preterm birth is associated with a higher risk of neurodevelopmental deficits, the aim of this review was to determine whether or not the advances in perinatal care that led to improved survival have also had a positive impact on long-term neurodevelopment. Studies examining temporal changes in neurodevelopment are limited, and only from high-income countries.

Regional brain volumes, microstructure and neurodevelopment in moderate-late preterm children.

Objective: To explore whether regional brain volume and white matter microstructure at term-equivalent age (TEA) are associated with development at 2 years of age in children born moderate-late preterm (MLPT).

Study Design: A cohort of MLPT infants had brain MRI at approximately TEA (38-44 weeks' postmenstrual age) and had a developmental assessment (Bayley Scales of Infant and Toddler Development and Infant Toddler Social Emotional Assessment) at 2 years' corrected age. Relationships between cortical grey matter and white matter volumes and 2-year developmental outcomes were explored using voxel-based morphometry.

Brain structure and neurological and behavioural functioning in infants born preterm.

Aim: To examine: (1) relationships between brain structure, and concurrently assessed neurological and behavioural functioning, in infants born preterm at term-equivalent age (TEA; approximately 38-44wks); and (2) whether brain structure-function relationships differ between infants born very (24-29wks) and moderate-late (32-36wks) preterm.

Method: A total of 257 infants (91 very preterm, 166 moderate-late preterm; 120 males, 137 females) had structural magnetic resonance imaging (MRI) and neurological and behavioural assessments (Prechtl's general movements assessment, Neonatal Intensive Care Unit Network Neurobehavioral Scale [NNNS] and Hammersmith Neonatal Neurological Examination [HNNE]). Two hundred and sixty-three infants (90 very preterm, 173 moderate-late preterm; 131 males, 132 females) had diffusion MRI and assessments.

Language in 2-year-old children born preterm and term: a cohort study.

Purpose: Language skills are critical. Children born very preterm are vulnerable to language problems, but further work is needed to determine characteristics and specific predictors of language problems in this population. We aimed to compare language outcomes between 2-year-old children born <30 weeks and their term-born peers; and to explore risk factors for language difficulties in this cohort.

The Baby Moves smartphone app for General Movements Assessment: Engagement amongst extremely preterm and term-born infants in a state-wide geographical study.

Aim: The Baby Moves smartphone application is designed for parents to video their infants' spontaneous movement for remote General Movements Assessment (GMA). We aimed to assess the engagement with Baby Moves amongst high- and low-risk infants' families and the socio-demographic variables related to engagement.

Methods: Families of extremely preterm (EP; <28 weeks' gestational age) or extremely low-birthweight (ELBW; <1000 g) infants and term-born controls from a state-wide geographical cohort study were asked to download Baby Moves.

Rates of early intervention services in children born extremely preterm/extremely low birthweight.

Aim: To determine the rates of early intervention (EI) service use in extremely preterm (EP, <28 weeks' gestation) or extremely low birthweight (ELBW, <1000 g) infants between 1991 and 2013, and identify biological or socio-economic factors associated with receiving EI.

Methods: Participants comprised consecutive EP or ELBW survivors born in 1991-1992, 1997 or 2005 in Victoria, Australia, and randomly selected, matched term-born controls. The main outcome measure was parent-reported EI participation up to 8 years of age.

Motor trajectories from birth to 5 years of children born at less than 30 weeks' gestation: early predictors and functional implications. Protocol for a prospective cohort study.

Introduction: Motor impairments are one of the most frequently reported adverse neurodevelopmental consequences in children born < 30 weeks' gestation. Up to 15% of children born at < 30 weeks have cerebral palsy and an additional 50% have mild to severe motor impairment at school age. The first 5 years of life are critical for the development of fundamental motor skills.

The contribution of visual processing to academic achievement in adolescents born extremely preterm or extremely low birth weight.

Children born extremely preterm (EP, <28 weeks) and/or extremely low birth weight (ELBW, <1000 g) have more academic deficiencies than their term-born peers, which may be due to problems with visual processing. The aim of this study is to determine (1) if visual processing is related to poor academic outcomes in EP/ELBW adolescents, and (2) how much of the variance in academic achievement in EP/ELBW adolescents is explained by visual processing ability after controlling for perinatal risk factors and other known contributors to academic performance, particularly attention and working memory. A geographically determined cohort of 228 surviving EP/ELBW adolescents (mean age 17 years) was studied.
