Maternal diet modulates the infant microbiome and intestinal Flt3L necessary for dendritic cell development and immunity to respiratory infectionPoor maternal diet during pregnancy is a risk factor for severe lower respiratory infections in the offspring, but the underlying mechanisms remain elusive. Here, we demonstrate that in mice a maternal low-fiber diet led to enhanced LRI severity in infants because of delayed plasmacytoid dendritic cell recruitment and perturbation of regulatory T cell expansion in the lungs.

Protection against neonatal respiratory viral infection via maternal treatment during pregnancy with the benign immune training agent OM-85Incomplete maturation of immune regulatory functions at birth is antecedent to the heightened risk for severe respiratory infections during infancy. Our forerunner animal model studies demonstrated that maternal treatment with the microbial-derived immune training agent OM-85 during pregnancy promotes accelerated postnatal maturation of mechanisms that regulate inflammatory processes in the offspring airways.

Whole-cell pertussis vaccine in early infancy for the prevention of allergyThis is a protocol for a Cochrane Review (intervention). The objectives were to assess the efficacy and safety of whole‐cell pertussis (wP) vaccinations in comparison to acellular pertussis (aP) vaccinations in early infancy for the prevention of atopic diseases in children.

Interaction between filaggrin mutations and neonatal cat exposure in atopic dermatitisRecent birth cohort studies showed a significant interaction between cat ownership at birth and mutations in FLG on the development of early‐onset atopic dermatitis

Time spent outdoors through childhood and adolescence - assessed by 25-hydroxyvitamin D concentration - and risk of myopia at 20 yearsTo investigate the relationship between time spent outdoors, at particular ages in childhood and adolescence, and myopia status in young adulthood using serum 25-hydroxyvitamin D [25(OH)D] concentration as a biomarker of time spent outdoors. Participants of the Raine Study Generation 2 cohort had 25(OH)D concentrations measured at the 6-, 14-, 17- and 20-year follow-ups. Participants underwent cycloplegic autorefraction at age 20 years, and myopia was defined as a mean spherical equivalent -0.50 dioptres or more myopic. Logistic regression was used to analyse the association between risk of myopia at age 20 years and age-specific 25(OH)D concentrations. Linear mixed-effects models were used to analyse trajectory of 25(OH)D concentrations from 6 to 20 years.

Primary prevention of severe lower respiratory illnesses in at-risk infants using the immunomodulator OM-85The effects of OM-85 were strongest in the first winter season, with a trend for fewer children in the OM-85 group to have sLRIs and URIs

Vitamin D deficiency at 16 to 20 weeks' gestation is associated with impaired lung function and asthma at 6 years of ageThis paper examines whether a Vitamin D deficiency during pregnancy affects the child's lung function predisposition towards lung disease such as asthma.

Genome-wide association study of vitamin D levels in children: replication in the Western Australian Pregnancy Cohort (Raine) studyThis genome-wide association study (GWAS) utilises data from the Western Australian Pregnancy Cohort (Raine) Study for 25-hydroxyvitamin D (25(OH)D) levels...
