Mothers with asthma or atopy have a higher likelihood of having autistic children, with maternal immune activation in pregnancy implicated as a mechanism. This study aimed to determine, in a prospective cohort of mothers with asthma and their infants, whether inflammatory gene expression in pregnancy is associated with likelihood of future autism.
Immunomodulatory proteins in human milk (HM) can shape infant immune development. However, strategies to modulate their levels are currently unknown. This study investigated whether maternal prebiotic supplementation alters the levels of immunomodulatory proteins in HM.
Growing evidence from preclinical studies, epidemiology, and randomized controlled trials supports a causal role for diet quality in mental disorder risk, and clinical psychiatric guidelines now place diet, along with other life-style behaviors, as foundational treatment targets for mood disorders.
Ingestion of prebiotics during pregnancy and lactation may have immunomodulatory benefits for the developing fetal and infant immune system and provide a potential dietary strategy to reduce the risk of allergic diseases. We sought to determine whether maternal supplementation with dietary prebiotics reduces the risk of allergic outcomes in infants with hereditary risk.
Infant allergy is the most common early manifestation of an increasing propensity for inflammation and immune dysregulation in modern environments. Refined low-fibre diets are a major risk for inflammatory diseases through adverse effects on the composition and function of gut microbiota. This has focused attention on the potential of prebiotic dietary fibres to favourably change gut microbiota, for local and systemic anti-inflammatory effects.

The ORIGINS Project (“ORIGINS”) is a longitudinal, population-level birth cohort with data and biosample collections that aim to facilitate research to reduce non-communicable diseases and encourage ‘a healthy start to life’. ORIGINS has gathered millions of datapoints and over 400,000 biosamples over 15 timepoints, antenatally through to five years of age, from mothers, non-birthing partners and the child, across four health and wellness domains.
Hepatitis B (HBV) prevalence is very high in pregnant women in the Dolpa district of Nepal, a region characterised by a remote geographic landscape and low vaccination coverage. Using mathematical modelling, we evaluated the impact of third-trimester tenofovir disoproxil fumarate (TDF) prophylaxis on HBV burden and estimated the time required to achieve HBV elimination in Dolpa.
Preeclampsia is a hypertensive disorder of pregnancy with major maternal and fetal consequences. While the molecular basis of early-onset preeclampsia is well studied, the mechanisms underlying late-onset disease-and how they differ by fetal sex-remain poorly understood. Placental transcriptomic profiling at term can reveal persistent molecular alterations reflecting cumulative disease processes.
We aimed to assess perceived stress and influencing factors in mothers with children at risk of type 1 diabetes and coeliac disease who did, or did not, develop islet autoantibodies or coeliac autoantibodies by 4 years of age.
