The association between prenatal pyrethroids exposure and children's health - current research.

Exposure to pyrethroids, a widely used agricultural, forestry, and household insecticide, is a major public health concern due to its potential health effects on children. The aim of this review was to summarize the current knowledge of the effects of prenatal exposure to pyrethroids on the course and outcome of pregnancy, health status, and neurobehavioural development of children. A systematic and comprehensive search of the PubMed, Web of Science, and Scopus databases was conducted during January-February 2024.

Peripheral blood immune parameters, response, and adverse events after neoadjuvant chemotherapy plus durvalumab in early-stage triple-negative breast cancer.

Purpose: We evaluated T- and B-cell receptor (TCR and BCR) repertoire diversity and 38 serum cytokines in pre- and post-treatment peripheral blood of 66 patients with triple-negative breast cancer (TNBC) who received neoadjuvant chemotherapy plus durvalumab and assessed associations with pathologic response and immune-related adverse events (irAEs) during treatment.

Methods: Genomic DNA was isolated from buffy coat for TCR and BCR clonotype profiling using the Immunoseq platform and diversity was quantified with Pielou's evenness index. MILLIPLEX MAP Human Cytokine/Chemokine Magnetic Bead Panel was used to measure serum cytokine levels, which were compared between groups using moderated t-statistic with Benjamini-Hochberg correction for multiple testing.

Prenatal polyunsaturated fatty acids and atopic dermatitis and food allergy in children from Polish Mother and Child Cohort study.

Objectives: Polyunsaturated fatty acids (PUFAs) are involved both in immune system regulation and inflammation. The aim of this prospective study was to evaluate the association between maternal dietary intake of PUFAs during pregnancy and atopic dermatitis (AD) and food allergy (FA) in their children up to 7-9 years of age.

Material And Methods: The study population consists of 557 mother-child pairs from the Polish Mother and Child Cohort (REPRO_PL).
