Seroconversion and seroreversion rates of anti-Strongyloides IgG in rural areas of the Amazon: a population-based panel study.

Using a panel study design, we aimed to estimate the seroconversion and seroreversion rates of anti-Strongyloides IgG antibodies from surveys carried out 11 months apart in a rural community in the Amazon Basin in Brazil. We used enzyme immunoassays to measure anti-Strongyloides IgG antibodies in 325 baseline plasma samples and 224 others that were collected 11 months later from residents in the agricultural settlement of Granada, Acre State. We observed anti-Strongyloides IgG antibodies in 21.

Information systems project success surveys - Insights from the last 30 years.

Information Systems (IS) projects have a long history of negative reputation regarding their success. However, studies that report the success of IS projects are generally focused on software development (which is only one of the many types of IS projects). Furthermore, practically no research compares the success achieved in the different types of IS projects and projects from other areas.

HBM4EU chromates study: the Portuguese integrated and harmonized study on exposure to hexavalent chromium and related early effects.

In the scope of the European Union (EU) human biomonitoring initiative, a multicentric study on different occupational settings from several European countries was performed, to provide information on occupational exposure to hexavalent chromium [Cr(VI)], a known lung carcinogen. Biomonitoring approaches were used to obtain exposure data to support the implementation of new risk management measures and policy actions at the national and European levels. This work describes the Portuguese contribution to the study, which aimed to assess workers' exposure to Cr, by using exposure biomarkers (urinary chromium [U-Cr]), and industrial hygiene samples (air and hand wipes) and to link exposure to potential long-term health effects by using effect biomarkers.

Aggressiveness of Care at the End of Life of Children Dying with Cancer in Public Hospitals-A Nationwide Retrospective Cohort Study.

Little is known about the aggressiveness of cancer care at the end of life (ACCEoL) for children with cancer in countries where palliative care (PC) is scarce. The aim of this study was to determine the frequency and time trends of ACCEoL in the pediatric population in a Western European country. We conducted a retrospective cohort study analyzing children between 0 and 17 years who died of cancer in public hospitals in Portugal, from January 2010 to December 2015.
