Background: The non-invasive assessment of maximal respiratory pressures (MRP) reflects the strength of the respiratory muscles.
Objective: To evaluate the studies which have established normative values for MRP in healthy children and adolescents and to synthesize these values through a meta-analysis.
Methods: The searches were conducted until October 2023 in the following databases: ScienceDirect, MEDLINE, CINAHL, SciELO, and Web of Science.
Ultrafine particles (< 100 nm) are of increasing concern because of their toxicological potential. Emission processes suggest their presence in all environments, including at home, where particularly at-risk populations may be exposed. However, knowledge of their impact on health is still limited, due to difficulties in properly assessing exposure in epidemiological studies.

Objective: This research study aimed to develop a predictive model to identify the risk of unplanned extubation in a pediatric intensive care unit (PICU).
Methods: This single-center, observational study was conducted at the PICU of the Hospital de Clínicas.
Modeling Primary Emissions of Chemicals from Liquid Products Applied on Indoor Surfaces.
Int J Environ Res Public Health
August 2022
Article Synopsis
- Household and personal care products can release chemicals into indoor air, leading to varying peak concentrations.
- A new model was created to better understand how these emissions occur, focusing on how liquids are absorbed and then re-emitted from surfaces and skin.
- The study found that the emission rates varied significantly; for example, up to 99% of chemicals could be emitted when applied to skin, and factors like material properties influenced these rates.
The indoor environmental quality in classrooms can largely affect children's daily exposure to indoor chemicals in schools. To date, there has not been a comprehensive study of the concentrations of semivolatile organic compounds (SVOCs) in French schools. Therefore, the French Observatory for Indoor Air Quality (OQAI) performed a field study of SVOCs in 308 nurseries and elementary schools between June 2013 and June 2017.
