Carbon monoxide affects early cardiac development in an avian model.

Introduction: Carbon monoxide (CO) is a toxic gas that can be lethal in large doses and may also cause physiological damage in lower doses. Epidemiological studies suggest that CO in lower doses over time may impact on embryo development, in particular cardiac development, however other studies have not observed this association.

Methods: Here, we exposed chick embryos in ovo to CO at three different concentrations (3, 9, 18 ppm) plus air control (4 protocols in total) for the first 9 days of development, at which point we assessed egg and embryo weight, ankle length, developmental stage, heart weight, ventricular wall thickness, ventricular-septal thickness and atrial wall thickness.

Commercial Baby Foods Aimed at Children up to 36 Months: Are They a Matter of Concern?

Proper nutrition in infancy and early childhood is crucial to ensuring optimal child development, growth, and better health outcomes later in life. The nutrient profile model proposed by WHO/Europe aims to assess the nutritional quality and promotional/marketing aspects of commercial baby foods aimed at children up to 36 months. We used commercial data from 191 baby foods collected between March 2021 and July 2021, from eight supermarket chains in the Lisbon Metropolitan area.

Breakfast Cereals Intended for Children: Opportunities for Reformulation and Potential Impact on Nutrient Intake.

Ready-to-eat cereals (RTECs) have become a popular breakfast option claiming to provide important nutrients to children's diets, despite being a source of excess sugar and, therefore, a health concern. Thus, food reformulation constitutes an important public health strategy that could benefit from inputs provided by nutrient profiling. This study aimed to assess the adequacy of the RTECs for children available in Portuguese supermarkets, applying three nutrient profile models (NPMs)-the nutrient profile model of the World Health Organization's Regional Office for Europe (WHO-EURO), the profile of the private-sector EU Pledge (EU-Pledge), and the national model developed by the Directorate-General of Health (NPM-PT)-in order to explore the potential for reformulation of the RTECs identified as not adequate and evaluate the impact of RTECs' reformulation on the nutritional quality of Portuguese children's diets.

Undergraduate Teaching in Geriatrics and Pediatrics in Portuguese Medical Schools: An Observational Study.

Introduction: Motivated by the contracting nature of the Portuguese age pyramid, and thereby the ever increasing geriatric population, the aim of this study was to compare the number of European Credit Transfer and Accumulation System Credits dedicated to Geriatrics with Pediatrics in Portuguese Medical Schools.

Material And Methods: An observational, descriptive and cross-sectional study was conducted and included six Portuguese Medical Schools that have six years of training and a total of 360 credits. The study plans were obtained from the medical schools' websites or requested.

The use of sensory perception indicators for improving the characterization and modelling of total petroleum hydrocarbon (TPH) grade in soils.

This paper proposes a multistep approach for creating a 3D stochastic model of total petroleum hydrocarbon (TPH) grade in potentially polluted soils of a deactivated oil storage site by using chemical analysis results as primary or hard data and classes of sensory perception variables as secondary or soft data. First, the statistical relationship between the sensory perception variables (e.g.
