Our Research

We aim to share our research findings with families so that they may better understand Rett syndrome and the future for their family.

Parental perspectives on the communication abilities of their daughters with Rett syndrome

We interviewed 17 parents with a daughter with Rett syndrome to gain their perspectives on how their daughter communicates and barriers.

Clinical severity and X-chromosome inactivation

For this study, we examined how Rett syndrome characteristics can be affected by X-inactivation for 2 of the common types of mutation - p.R168X and p.T158M.

Feeding experiences and growth status in a Rett syndrome population

We set out to describe the feeding difficulties and nutrition of girls with Rett syndrome and to examine what factors may be influencing their nutrition.

Longitudinal hand function in Rett syndrome

Therefore, we used video data to examine changes in hand function over time. We also investigated what other factors might influence these changes.

Penicillin G concentrations required for prophylaxis against Group A Streptococcus infection evaluated using a hollow fibre model and mathematical modelling

Acute rheumatic fever (ARF), an autoimmune reaction to Group A Streptococcus (Streptococcus pyogenes; Strep A) infection, can cause rheumatic heart disease (RHD). New formulations of long-acting penicillins are being developed for secondary prophylaxis of ARF and RHD.

Research

Mapping malaria by sharing spatial information between incidence and prevalence data sets

As malaria incidence decreases and more countries move towards elimination, maps of malaria risk in low-prevalence areas are increasingly needed. For low-burden areas, disaggregation regression models have been developed to estimate risk at high spatial resolution from routine surveillance reports aggregated by administrative unit polygons.

Longitudinal Evaluation of the Stability of Hand Function in Rett Syndrome

We investigated the longitudinal stability of hand function in Rett syndrome and to analyze further the relationships between stability of hand function and genotype, age, and walking ability. Study design: Longitudinal video data of functional abilities of individuals with genetically confirmed Rett syndrome were collected by families of individuals registered with the Australian Rett Syndrome Database.

Prevalence and predictors of vitamin D deficiency in a nationally representative sample of Australian Aboriginal and Torres Strait Islander adults

Vitamin D deficiency (serum 25-hydroxyvitamin D (25(OH)D) concentration <50 nmol/l) is recognised as a public health problem globally. The present study details the prevalence and predictors of vitamin D deficiency in a nationally representative sample of Australian Aboriginal and Torres Strait Islander adults aged >/=18 years.

Fuel feedstock determines biodiesel exhaust toxicity in a human airway epithelial cell exposure model

Biodiesel is promoted as a sustainable replacement for commercial diesel. Biodiesel fuel and exhaust properties change depending on the base feedstock oil/fat used during creation. The aims of this study were, for the first time, to compare the exhaust exposure health impacts of a wide range of biodiesels made from different feedstocks and relate these effects with the corresponding exhaust characteristics.
