Atmospheric pollution and mortality in Portugal: Quantitative assessment of the environmental burden of disease using the AirQ+ model.

In Portugal, data on mortality rate attributed to household and ambient air pollution are not reported due to shortness and irregularity of the available data series, and therefore, the disclosure of the national progress in reducing the number of deaths and illnesses from air contamination in exposures to multiple pollutants is incomplete. The present work describes the application of the AirQ+ model developed by the WHO to calculate how much of specific health outcomes is attributable to long-term exposure to atmospheric NO2, PM2.5, and O3 in the population of various municipalities in Portugal, from 2010 to 2019. Linear Mixed Models were used for data analysis and have shown that (i) approximately 5000 deaths per year are attributable to exposure to mixtures of NO2 and PM2.5; (ii) the spatial distribution of the proportion of deaths attributable to NO2, PM2.5 and O3 shows significant differences between locations, and (iii) that AirQ+ is a useful tool for the purpose of effective Public Health policymaking and reporting on the national progress to implement the 2030 Agenda.

Nutritional status assessment in colorectal cancer patients.

The present study intended to evaluate the nutritional status of Portuguese colorectal patients and associated it with surgery type as well as quality of life outcomes. Malnutrition can affect up to 85% of cancer patients and specifically 30-60% in colorectal cancer and can significantly influence health outcomes. A sample of 50 colorectal cancer patients was evaluated in what refers to several anthropometric measures, food intake, clinical history, complications rate before and after surgery procedure. The sample was divided between convention and fast-track procedures. Most of the individuals were overweight or obese but had lost weight on the past six months. Despite mild, there were signs of malnutrition in this sample with high losses of fat free mass, weight and also fat mass during the hospitalization period. These results reinforce the importance of malnutrition assessment in colorectal patients as well as consider weight loss on the past months and body composition in order to complement nutritional status evaluation.

El presente estudio pretende evaluar el estado nutricional de enfermos de cáncer colorectal portugueses teniendo en cuenta el tipo de cirugía y indicativos de calidad de vida. La malnutrición suele afectar hasta 85% de los enfermos de cáncer y 30-60% entre los de cáncer colorectal y puede afectar significativamente las mejorías de salud. Se ha completado una evaluación antropométrica de 50 individuos admitidos en un hospital portugués para cirugía incluido también ingestión alimentaria, historia clínica, complicaciones antes y después de la cirugía. La muestra ha sido dividida entre el procedimento quirúrgico convencional y el fast-track. La mayoría de los individuos era obesa ó tenía sobrepeso pero había perdido peso en los últimos 6 meses antes de entrar en el hospital. Aunque poco severas, tenían señales de malnutrición con grandes pérdidas de masa magra, peso y también grasa corporal durante el período en el hospital. Estés resultados han reenfocado la importancia de una evaluación nutrición en enfermos de cáncer, sobretodo colorectal teniendo en cuenta el peso perdido pero también la composición corporal para que se complete el protocolo de evaluación nutricional.
