We report a role for MCs within the developing fetus and demonstrate that fetal MCs may contribute to antigen-specific vertical transmission of allergic disease.

CONCLUSION: Higher PM2.5 during the first trimester of pregnancy and low CB vitamin D affected early onset persistent AD, and the most sensitive window was weeks 6-7 of gestation. Placental DNA methylation mediated this effect. PMID: 32971247 [PubMed - as supplied by publisher]

a M, Virtanen SM Abstract Cow's milk allergy (CMA) is the most common food allergy in young children and it is often the first manifestation of atopic diseases. Accordingly, very early environmental factors, such as maternal diet during pregnancy, may play a role in the development of CMA, but the evidence is limited. The aim of this study was to investigate the association between maternal intake of antioxidant nutrients during pregnancy and the subsequent development of CMA in the offspring in a prospective, population-based birth cohort within the Finnish Type 1 Diabetes Prediction and Prevention Study. Materna...

Wondering when to get your flu shot? The best time is before influenza (flu) starts circulating widely. For most people, September or October is ideal for protection through the whole flu season, as the immune response from the vaccine wanes over time. And while changes and restrictions due to COVID-19 may make getting a flu vaccine less convenient for some this year, the pandemic makes it more important than ever. Why do I need to get a flu vaccine yearly? Influenza A and Influenza B cause most cases of flu in humans. Both have many strains that constantly change, accumulating genetic mutations that disguise them from the...

Conclusions. Our preliminary findings suggest that maternal egg intake during pregnancy might be a factor influencing laboratory markers of atopy in ofsprings. Prospective cohort studies are needed to confirm and clarify this relationship. PMID: 32914946 [PubMed - as supplied by publisher]

Abstract OBJECTIVE: Exposome encompasses all human environmental exposures from conception onwards. The impact of environmental exposures is greatest in critical stages of life including fetal and early childhood. Birth cohorts provide a good study setting to assess exposome in the sensitive periods of life. Here, we review birth cohorts with an exposomic approach, their key outcomes and challenges. DATA SOURCES: MEDLINE was searched for birth cohorts that have employed an exposomic approach. Study Selections Relevant studies in English language were selected and reviewed. RESULTS: The outcomes of birth ...
