A wastewater-based epidemiology tool for COVID-19 surveillance in Portugal

The presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in wastewater produced interest in its use for sentinel surveillance at a community level and as a complementary approach to syndromic surveillance. With this work, we set the foundations for wastewater-based epidemiology (WBE) in Portugal by monitoring the trends of SARS-CoV-2 RNA circulation in the community, on a nationwide perspect...

Determinants of maternal health care and birth outcome in the Dande Health and ...

Maternal health care improvement and reduction of maternal and child mortality are priorities of the global health agenda. In Angola, maternal mortality remains high and the risk of pregnancy-related death was 1 in 32 during 2015. This study aims to identify demographic and social factors influencing antenatal care and health facility delivery among women in Dande and to understand their impact on birth outcome...

Occupational exposure to formaldehyde: exposure and genotoxic effects assessment

Since 2004, formaldehyde (FA) has been classified by the International Agency for Cancer Research as a carcinogen. The FA ranks 25th in the overall United States chemical production, with more than 5 million tons produced each year. Due to its economic importance and varied use, many individuals are exposed to FA in their occupational settings. This study aimed to assess the exposure to FA in two occupational s...

Exposição ocupacional a formaldeído: avaliação da exposição e efeitos genotóxicos

O formaldeído (FA) foi classificado, em 2004, pela International Agency for Cancer Research como agente cancerígeno. Este agente químico ocupa a 25ª posição em toda a produção química dos Estados Unidos da América, com mais de 5 milhões de toneladas produzidas por ano. Devido à sua importância económica e uso diversificado, muitos indivíduos estão expostos profissionalmente a FA. Com o estudo desenvolvido prete...

Genotoxicity biomarkers: application in histopathology laboratories

Most cancers results from man-made and natural environmental exposures (such as tobacco smoke; chemical pollutants in air, water, food, drugs; radon; and infectious agents) acting in concert with both genetic and acquired characteristics. It has been estimated that without these environmental factors, cancer incidence would be dramatically reduced, by as much as 80%-90%. The modulation of environmental factors ...
