Comparison of Weight-Gain-Based Prediction Models for Retinopathy of Prematurity in an Australian Population.

Purpose: Four weight-gain-based algorithms are compared for the prediction of type 1 ROP in an Australian cohort: the weight, insulin-like growth factor, neonatal retinopathy of prematurity (WINROP) algorithm, the Children's Hospital of Philadelphia Retinopathy of Prematurity (CHOPROP), the Colorado Retinopathy of Prematurity (CO-ROP) algorithm, and the postnatal growth, retinopathy of prematurity (G-ROP) algorithm.

Methods: A four-year retrospective cohort analysis of infants screened for ROP in a tertiary neonatal intensive care unit in Brisbane, Australia. The main outcome measures were sensitivities, specificities, and positive and negative predictive values.

Anterior eye tissue morphology: Scleral and conjunctival thickness in children and young adults.

The sclera and conjunctiva form part of the eye's tough, protective outer coat, and play important roles in the eye's mechanical protection and immune defence, as well as in determining the size and shape of the eye globe. Advances in ocular imaging technology now allow these tissues in the anterior eye to be imaged non-invasively and with high resolution, however there is a paucity of data examining the dimensions of these tissues in paediatric populations. In this study, we have used optical coherence tomography (OCT) imaging to examine the normal in vivo thickness profile of the anterior sclera and overlying conjunctiva in 111 healthy young participants, including a large proportion of paediatric subjects.

Local community playgroup participation and associations with social capital.

Issue addressed The study aim was to investigate the relationships between social capital measures and playgroup participation in a local residential area for parents with children of playgroup age (1-4 years) compared with non-participation and participation in a playgroup outside the local residential area. Research indicates playgroup participation has benefits for families, however, less is known about the potential local community social capital for parents who participate in playgroups. Methods Data were collected through a cross-sectional survey from March 2013 to January 2014 in Perth, Western Australia.
