Article Synopsis
  • The study investigates how the nasal microbiome differs between children with allergic rhinitis (AR) and healthy controls, looking at various sample types (nasal, dermal, oral, dust).
  • It finds that the diversity of dust microorganisms is lower in AR children, and significant differences in bacterial composition exist in the nasal, skin, and dust samples compared to controls, with specific bacterial species being more abundant in AR children.
  • The analysis reveals that Staphylococcus epidermidis and Staphylococcus aureus are more prevalent in AR children’s nasal cavities, with higher transfer rates of S. epidermidis from the nasal cavity to skin and dust compared to healthy subjects.

The aim was to study associations between dialkylphosphates (DAPs), organophosphate (OP) metabolites in urine, biomarkers of OP insecticide exposure, and respiratory symptoms among children in upper northern Thailand. We recruited junior high school children in randomly selected schools in four cities (N = 337), with repeated data collection in wet and dry seasons. Urine was collected and analyzed for six OP metabolites, with creatinine adjustment.

Objective: To study associations between fractional exhaled nitric oxide (FeNO) and asthma, airway symptoms, sensitization to common allergens, outdoor pollution and home environment among 380 students in eight junior high schools in two areas in Indonesia.

Methods: Data on health and home were collected by a face-to face interview before measuring FeNO and performing skin prick test against common allergens. Exploratory linear mixed and logistic regression models were employed.

The impact of early life exposure to residential greenness on childhood rhinitis and its interaction with particulate matter (PM) of different size fractions remain inconsistent. Herein, we recruited 40,486 preschool children from randomly selected daycare centers in 7 cities in China from 2019 to 2020, and estimated exposure to residential greenness by the normalized difference vegetation index (NDVI) with a 500 m buffer. Exposure to ambient PM (PM, PM and PM) was evaluated using a satellite-based prediction model (daily, at a resolution of 1 km × 1 km).

Background: Few studies focus on the associations of green space composition and configuration with children's allergic rhinitis (AR).

Methods: A multi-center population-based cross-sectional study was performed in 7 cities in mainland of China between 2019 and 2020, recruiting 36,867 preschool children. Information on the current AR symptoms and demographics were collected by questionnaire.
