The incidence of upper respiratory infections in children is related to the concentration of vanadium in indoor dust aggregates.

Background: It has been reported that the disease-initiated and disease-mediated effects of aerosol pollutants can be related to concentration, site of deposition, duration of exposure, as well as the specific chemical composition of pollutants.

Objectives: To investigate the microelemental composition of dust aggregates in primary schools of Vilnius and determine trace elements related to acute upper respiratory infections among 6-to 11-year-old children.

Methods: Microelemental analysis of aerosol pollution was performed using dust samples collected in the classrooms of 11 primary schools in Vilnius from 2016 to 2020.

Vaccine-hesitant families are more susceptible to verbal communication messaging.

Objectives: Our survey aims to highlight parents' and healthcare workers' opinions and hesitations regarding children's vaccination, identify the main factors influencing these opinions, and assess the impact of hesitations on immunisation for children, included in the National Immunisation Programme in Lithuania.

Methods: We used the questionnaire developed by the European Academy of Paediatrics Research in Ambulatory Settings Network (EAPRASnet). This questionnaire is designed to assess attitudes toward vaccination.
