Longitudinal bone mineral content and density in Rett syndrome and their contributing factors

Bone mass and density are low in females with Rett syndrome.

Vitamin D in fetal development: Findings from a birth cohort study

Birth cohort studies provide an invaluable resource for studies of the influence of the fetal environment on health in later life.

Optimization is required when using linked hospital and laboratory data to investigate respiratory infections

Despite a recommendation for microbiological testing, only 45% of children hospitalized for respiratory infections in our previous data linkage study linked...

Does late childbearing increase the risk for behavioural problems in children? A longitudinal cohort study

This study aimed to examine the relationship between advanced parental age and behavioural outcomes in offspring in a longitudinal cohort of children in...

Heritable and environmental determinants of hospitalisation for common childhood illnesses

We will leverage the unique Western Australian data linkage resources to undertake the definitive twin and sibling study of infection-related hospitalisation

Zika Virus Changes Methylation of Genes Involved in Immune Response and Neural Development in Brazilian Babies Born With Congenital Microcephaly

The recent increase in babies born with brain and eye malformations in Brazil is associated with Zika virus (ZIKV) infection in utero. ZIKV alters host DNA methylation in vitro. Using genome-wide DNA methylation profiling we compared 18 babies born with congenital ZIKV microcephaly with 20 controls. We found ZIKV-associated alteration of host methylation patterns, notably at RABGAP1L which is important in brain development, at viral host immunity genes MX1 and ISG15, and in an epigenetic module containing the causal microcephaly gene MCPH1. Our data support the hypothesis that clinical signs of congenital ZIKV are associated with changes in DNA methylation.

Perinatal risk factors associated with skin infection hospitalisation in Western Australian Aboriginal and Non-Aboriginal children

We have quantified the relative influence of perinatal risk factors associated with skin infection hospitalisations in WA children

Acellular Pertussis Vaccine Given in the Week After Birth Does Not Impair Antibody Responses to Later Childhood Doses

A birth acellular pertussis vaccine may be a valuable alternative for immunity against infant pertussis when a pregnancy pertussis vaccine has not been administered. We assessed whether a birth dose may impair immunoglobulin G (IgG) responses to childhood pertussis boosters.

Immunogenicity and Safety of a 2 + 1 DTPa Priming Schedule in Australian Infants and the Impact of Maternally Derived Antibodies on Pertussis Antibody Responses up to 4 Years of Age

We assessed the impact of maternally derived pertussis antibodies on infant responses to a 2 + 1 vaccine schedule (6 weeks, 12 weeks, and 12 months). Infants with baseline antibodies showed lower IgG responses following the primary vaccination series, but this did not impair booster responses at 4 years of age.

Immunogenicity of the inactivated influenza vaccine in children who have undergone allogeneic haematopoietic stem cell transplant

This study provides evidence to support annual inactivated influenza vaccine administration to children following allogeneic haematopoietic stem cell transplant
