Ventilatory response and stability of oxygen saturation during a hypoxic challenge in very preterm infants

Preterm infants have immature control of breathing and impaired pulmonary gas exchange. We hypothesized that infants with bronchopulmonary dysplasia (BPD) have a blunted ventilatory response and peripheral oxygen saturation (SpO2 ) instability during a hypoxic challenge.

Gestational age at birth and body size from infancy through adolescence: An individual participant data meta-analysis on 253,810 singletons in 16 birth cohort studies

Preterm birth is the leading cause of perinatal morbidity and mortality and is associated with adverse developmental and long-term health outcomes, including several cardiometabolic risk factors and outcomes. However, evidence about the association of preterm birth with later body size derives mainly from studies using birth weight as a proxy of prematurity rather than an actual length of gestation. We investigated the association of gestational age (GA) at birth with body size from infancy through adolescence.

Development of prognostic model for preterm birth using machine learning in a population-based cohort of Western Australia births between 1980 and 2015

Preterm birth is a global public health problem with a significant burden on the individuals affected. The study aimed to extend current research on preterm birth prognostic model development by developing and internally validating models using machine learning classification algorithms and population-based routinely collected data in Western Australia.

Early mortality among aboriginal and non-Aboriginal women who had a preterm birth in Western Australia: A population-based cohort study

Having a preterm (<37 weeks' gestation) birth may increase a woman's risk of early mortality. Aboriginal and Torres Strait Islander women have higher preterm birth and mortality rates compared with other Australian women.

Airway smooth muscle thickness and contraction are enhanced by intra-amniotic lipopolysaccharide in an ovine model of premature birth

Abnormalities of the airway smooth muscle (ASM) layer in asthma may develop before birth. We hypothesize that antenatal inflammation causes physiological abnormalities of the ASM that predisposes asthma. This study determined the short-term effects of antenatal inflammation on the developing ASM.

Diaphragm Function in Very Preterm Infants at 36 Weeks' Postmenstrual Age

Understand how bronchopulmonary dysplasia (BPD) and antenatal and postnatal factors influence diaphragmatic functional effectiveness in very preterm infants.

Lung volumes, gas transfer and oscillometry after preterm birth: systematic review and meta-analysis

Small airway and lung parenchymal abnormalities frequently occur following preterm birth but are commonly missed by spirometry. Static lung volumes, diffusing capacity of the lung for carbon monoxide (D LCO) and oscillometry provide a more precise characterisation of these conditions. We hypothesised that differences in these measures exist between individuals born preterm and at term and we aimed to systematically review the literature to identify and quantify these differences in lung function.

A primary cell model of the very preterm epithelium reveals barrier defects at 1 year of age

Limited evidence suggests that airway epithelial structure and function is disrupted in very preterm infants; however, the epithelial morphology and physiology has not been well characterised following discharge from neonatal intensive care. This study aimed to characterise the nasal airway epithelium from 1-year-old survivors of very preterm birth.

Physiological responses to exercise in survivors of preterm birth: a meta-analysis

Survivors of preterm birth (<37 weeks' gestation) have low peak oxygen uptake, a global measure of aerobic fitness and an established predictor of increased morbidity and mortality. However, little is known about other cardiopulmonary outcome measures in this population. We addressed the hypothesis that preterm birth is associated with abnormal respiratory, cardiovascular and metabolic responses to exercise, as assessed by cardiopulmonary exercise testing, via a systematic review and meta-analysis.

Exercise training to address lifelong consequences of preterm birth: a survey of perceived needs

The identification of a COPD etiotype associated with preterm birth (COPD-developmental) has expedited calls for intervention strategies that may improve health outcomes for survivors of preterm birth (<37 weeks' gestation). Pulmonary-rehabilitation style training interventions achieve physiological and symptom improvement in older people with COPD, but whether similar training interventions are suitable for young people is unclear. We sought to understand the perceived need and requirements of an exercise training intervention for children, adolescents and adults born preterm.
