An overview of work-related stress assessment
Lavreysen, Olivia; Bakusic, Jelena; Abatzi, Thalia-Anthi; Geerts, Annelien; Mateusen, Mies; Bashkin, Osnat; Koscec Bjelajac, Adrijana; Dopelt, KerenObjective: Work-related stress (WRS) is associated with the development of various health issues and long-term absence from the workplace. Adequate measurement of WRS is essential to assess its prevalence, risks, and effectiveness of preventive interventions. The aim of this review was to provide an overview of different categories of WRS assessment: 1) self-assessment, 2) external assessment, and 3) biomarkers...
Development and In Vitro Validation of Antibacterial Paints Containing Chloroxy...
Querido, Micaela Machado; Paulo, Ivo; Hariharakrishnan, Sriram; Rocha, Daniel; Barbosa, Nuno; Gonçalves, Diogo; dos Santos, Rui GalhanoThe establishment of self-disinfecting surfaces is an important method to avoid surface contamination. Recently, paints with antimicrobial properties have been developed to be applied on different surfaces, avoiding contamination with pathogens. In this work, self-disinfecting paints containing Chloroxylenol (CLX), Terpineol (TRP), and a mixture of both substances were developed. The goal was to evaluate and va...
Development of a new multiplex PCR to detect prevalent species of house dust mi...
Oliveira, Ana Sofia; Gaspar, Carlos; Rolo, Joana; Pereira, Cristiana Costa; Palmeira-de-Oliveira, Rita; Teixeira, João Paulo; Martinez-de-Oliveira, JoséDermatophagoides pteronyssinus and Dermatophagoides farinae are the most common House Dust Mite (HDM) species in home environments worldwide and responsible for HDM allergy. Since the prevalence of HDM-related clinical conditions is linked to exposure to the mite itself, the detection of HDM in the human households gains importance. We aimed to develop a fast and accessible multiplex PCR to detect and distingui...
DNA damage in circulating leukocytes measured with the comet assay may predict ...
Bonassi, Stefano; Ceppi, Marcello; Møller, Peter; Azqueta, Amaya; Milić, Mirta; Monica, Neri; Brunborg, Gunnar; Godschalk, Roger; Koppen, GudrunThe comet assay or single cell gel electrophoresis is the most common method used to measure strand breaks and a variety of other DNA lesions in human populations. To estimate the risk of overall mortality, mortality by cause, and cancer incidence associated with DNA damage, a cohort of 2,403 healthy individuals (25,978 person-years) screened in 16 laboratories using the comet assay between 1996 and 2016 was fo...
Self-Disinfecting Paints with the Natural Antimicrobial Substances: Colophony a...
Querido, Micaela Machado; Paulo, Ivo; Hariharakrishnan, Sriram; Rocha, Daniel; Barbosa, Nuno; Galhano dos Santos, Rui; Bordado, João MouraThe risk of infection arising from indirect sources-namely, contaminated surfaces-has been proved, particularly in healthcare facilities. In the attempt to minimize this problem, innumerable research projects involving the development of surfaces with self-disinfecting properties are being conducted. In this work, wall-paints with self-disinfecting properties were developed with the scope of being applied in en...
Auto-Disinfectant Acrylic Paints Functionalised with Triclosan and Isoborneol -...
Machado Querido, Micaela; Paulo, Ivo; Hariharakrishnan, Sriram; Rocha, Daniel; Pereira, Cristiana Costa; Barbosa, Nuno; Bordado, João MouraEnvironmental surface contamination with microorganisms is a serious concern worldwide. Triclosan and isoborneol present good antimicrobial activity. Their immobilisation to paint substrates allows for development of a material that stays effective over a longer time. In this work, we disclosed the preliminary studies to evaluate the antimicrobial activity of the active molecule after being functionalised with ...

Self-Disinfecting Surfaces and Infection Control
Querido, Micaela Machado; Aguiar, Lívia; Neves, Paula; Pereira, Cristiana Costa; Teixeira, João PauloAccording to World Health Organization, every year in the European Union, 4 million patients acquire a healthcare associated infection. Even though some microorganisms represent no threat to healthy people, hospitals harbor different levels of immunocompetent individuals, namely patients receiving immunosuppressors, with previous infections, or those with extremes of age (young children and elderly), requiring ...
Endotoxin levels in forklift’s filters and the importance of maintenance enforc...
Pereira, Cristiana Costa; Lage, Bruna; Teixeira, João Paulo; Viegas, CarlaMany studies have already linked endotoxin exposure, especially in workplaces, to airways disease, yet threshold limit values have not been set, nor a standardized procedure for the analysis of endotoxin levels. Inhaled endotoxins may cause bronchial asthma and may increase the allergic response in hypersensitive people. Endotoxins are biologically active lipopolysaccharides (LPSs) produced by the most external...
RESPIRA Project: Understanding the role of environmental contaminants in respir...
Sousa, Ana Catarina; Miranda, Sara; Marques, Alda; Valente, Carla; Amoro, Raquel; Pereira, Cristiana Costa; Teixeira, João Paulo; Silva, TatianaIn the last century, there was a shift from an outdoor to an indoor lifestyle and presently we spend 80- 90% of our lives inside buildings. This artificial habitat has unique features (e.g. insulation, humidity) that promote the accumulation of not only biological agents (e.g. bacteria, fungi) but also chemical contaminants; therefore, it is a prime interface between such agents and humans. However, humans are ...
