Background: The increase in allergic diseases in children has coincided with the westernization of lifestyles. Although clustering of modifiable lifestyles has been frequently reported in children, there is limited research on how lifestyle factors collectively contribute to allergic conditions. Our aim was to identify lifestyle clusters among Finnish school-aged children and explore their associations with the prevalence of allergic disease symptoms and sensitization.

Article Synopsis
  • - This study compares human milk antibodies to various pathogens in women from five different countries (Bangladesh, Finland, Peru, Pakistan, and the U.S.) using advanced protein microarrays, analyzing samples from 695 women.
  • - Results reveal that antibody levels, specifically IgA and IgG, vary significantly by region and are influenced by factors like maternal BMI and number of children, with the highest antibody coverage found in Bangladeshi and Pakistani mothers.
  • - The findings suggest that certain human milk antibodies may provide protective benefits against infections in infants, which could inform strategies to reduce infant illness and mortality globally.

Perinatal and early-life factors reported to affect risk of allergic diseases may be mediated by changes in the gut microbiota. Here, we explored the associations between the infant gut microbiota and allergic morbidity in childhood until 13 years of age in a subgroup of the FLORA probiotic intervention cohort. A mixture of four probiotic strains with galacto-oligosaccharides was administrated to the mothers from the 36th week of the pregnancy and later to their infants until 6 months of age.

Background: Milk oral immunotherapy (OIT) may increase the amount of milk protein that can be ingested without triggering an allergic reaction. It is important to understand why some patients benefit from the treatment while others do not.

Objective: The aim was to define the differences in the milk allergen component-specific (casein, α-lactalbumin, ß-lactoglobulin) immunoglobulin (sIg [sIgE, sIgG4, and sIgA]) levels relative to the long-term outcomes of milk OIT.

Accumulating evidence indicates that gut microbiota may regulate sex-hormone levels in the host, with effects on reproductive health. Very little is known about the development of intestinal microbiota during puberty in humans. To assess the connection between pubertal timing and fecal microbiota, and to assess how fecal microbiota develop during puberty in comparison with adult microbiota, we utilized a Finnish allergy-prevention-trial cohort (Flora).

Background: Probiotics have shown promising results in primary prevention of allergies in early years, but the long-term effects on allergic sensitization need more evaluation.

Objectives: We conducted a randomized double-blind placebo-controlled study to determine whether the use of a mixture of pre- and probiotics perinatally affects the prevalence of immunoglobulin E (IgE) sensitization up to 13 years in high-risk children.

Methods: One thousand two hundred twenty-three pregnant women were randomized to receiving probiotics or placebo from 36 gestational weeks until delivery, and their infants received pre- and probiotics or placebo from birth until 6 months.

Background: The safety and efficacy of long-term milk oral immunotherapy (OIT) in Finnish children with persistent cow's milk allergy (CMA) were evaluated in an open-label, non-randomized study.

Methods: During the 11-year study, 296 children aged 5 years or older with immunoglobulin E (IgE)-mediated CMA started milk OIT. Follow-up data were collected at three time points: the post-buildup phase, 1 year thereafter, and at the cross-sectional long-term follow-up between January 2016 and December 2017.

Building on theories of valuation and evaluation, we develop an analytical framework that outlines six elements of the process of consolidation of an idea in the public sphere. We then use the framework to analyse the process of consolidation of the idea of climate change mitigation between 1997 and 2013, focusing on the interplay between ecological and economic evaluations. Our content analysis of 1274 articles in leading newspapers in five countries around the globe shows that (1) ecological arguments increase over time, (2) economic arguments decrease over time, (3) the visibility of environmental nongovernmental organizations as carriers of ecological ideas increases over time, (4) the visibility of business actors correspondingly decreases, (5) ecological ideas are increasingly adopted by political and business elites and (6) a compromise emerges between ecological and economic evaluations, in the form of the argument that climate change mitigation boosts, rather than hinders economic growth.

Probiotics are theoretically promising in primary prevention of celiac disease (CD), but research evidence on the topic is scarce. We used the data and material of a clinical double-blind randomized placebo-controlled trial on primary allergy prevention (n = 1223) to investigate in an exploratory study whether administration of a mix of pro- and prebiotics during late pregnancy and first 6 months of life was associated with prevalence of CD during 13-year follow-up. Children who fulfilled diagnostic criteria for CD (n = 11) and subjects with a serum sample available for analyzing CD antibodies (n = 867) were included.
