Firefighters' occupational exposure to air pollution: impact on COPD and asthma-study protocol.

Introduction: Firefighting continues to be among the most hazardous yet least studied occupations in terms of the impact of exposure to occupational disease. In particular, firefighters are at increased risk of adverse health effects due to exposure to significant levels of potentially harmful substances, namely carbon monoxide, particulate matter and formaldehyde, during their professional duties.This paper reports an epidemiologic study aiming to reduce the gaps in assessing the long-term effects of air pollution exposure to forest fires' combat on firefighters, namely regarding chronic obstructive pulmonary Disease (COPD) and asthma.

Occupational exposure of firefighters to hazardous pollutants during prescribed fires in Portugal.

Firefighters perform high-risk activities and during the course of their functions are highly exposed to a wide range of occupational hazards, including air pollution. Thus, this study aimed to assess the exposure of firefighters in prescribed wildland fires and their occupational exposure, as well as to identify and chemically characterise the particles collected during wildland firefighting and inside fire stations. Exposure to wildfire smoke was evaluated in 7 prescribed fires in Portugal, 2 in the north and 5 in the south of Viseu district.

Health and economic burden of wildland fires PM-related pollution in Portugal - A longitudinal study.

Portugal has been affected by wildland fires that destroy thousands of hectares of forest, causing damage to the environment and to the exposed populations. This study aims to assess the influence of wildland fire emissions on air quality, its effect on population health and the related costs, between 2015 and 2018 in Portugal. The cause-specific mortality due to PM was calculated considering the exposure for five endpoints in adults, twelve age groups for adults and considering children under five years old.

Novel Approach for a Controlled Delivery of Essential Oils during Long-Term Maize Storage: Clove Bud and Pennyroyal Oils Efficacy to Control , Reducing Grain Damage and Post-Harvest Losses.

Maize grains represent a significant contribution for assuring food safety all over the globe. (Motschulsky) (Coleoptera: Curculionidae), also known as the maize weevil, is one of the most destructive pests in stored maize, causing qualitative and quantitative losses. To control populations in maize storage sites, synthetical chemical insecticides are applied.

The Effect of Fire Smoke Exposure on Firefighters' Lung Function: A Meta-Analysis.

Firefighters are exposed to a range of harmful substances during firefighting. Exposure to fire smoke has been associated with a decrease in their lung function. However, the cause-effect relationship between those two factors is not yet demonstrated.

Increasing prevalence of obesity and diabetes among patients evaluated for liver transplantation in a Swiss tertiary referral center: a 10-year retrospective analysis.

Background And Aims: Non-alcoholic fatty liver disease (NAFLD) is now the first cause of chronic liver disease in developed countries. We aimed to assess trends in the prevalence of obesity, type 2 diabetes mellitus (T2DM) and NAFLD in patients undergoing liver transplantation evaluation and to assess whether obese patients were less likely to be listed or had an increased drop-out rate after listing.

Methods: We conducted a retrospective study of all consecutive patients who underwent liver transplantation evaluation at a Swiss tertiary referral centre between January 2009 and March 2020.

Health and Economic Burden of the 2017 Portuguese Extreme Wildland Fires on Children.

Wildland fires release substantial amounts of hazardous contaminants, contributing to a decline in air quality and leading to serious health risks. Thus, this study aimed to understand the contributions of the 2017 extreme wildland fires in Portugal on children health, compared to 2016 (with burned area, in accordance with the average of the previous 15 years). The impact of long-term exposure to PM and NO concentrations, associated with wildland fires, on postneonatal mortality, bronchitis prevalence, and bronchitis symptoms in asthmatic children was estimated, as well as the associated costs.
