Personal characteristics and transmission dynamics associated with SARS-CoV-2 semi-quantitative PCR test results: an observational study from Belgium, 2021-2022.
PCR test (SQ- PCR) results, used as a proxy for viral load, were routinely collected after performing RT-qPCR tests. METHODS: We investigated both the personal characteristics associated with SQ- PCR ...
What drives the long-term changes in airborne birch and grass pollen levels in Belgium?
two scenarios: 1. Reference Scenario (i): SILAM was run for 38 seasons with a fixed emission map of birch and grass pollen sources. Variations in airborne pollen levels result solely from changes in ...
Analyzing the airborne birch and grass pollen monitoring network in Belgium
mode (three days), determining the trajectory of birch and grass pollen observed at the network stations. Nine pollen seasons (2013–2021) were analyzed using ECMWF ERA5 meteorology. Results The network ...
Estimating the Uncertainty in Airborne Birch Pollen Modelling
native grid), we randomly redistributed the birch pollen emission sources 100 times. From the resulting 100 SILAM model runs, 100 spatial-temporal datasets on surface birch pollen levels were produced, and ...
Evaluation of European Pollen Reanalysis
reanalysis is generally unbiased by its design. However, predictions in some individual years and at specific stations could manifest noticeable deviations, offset in other years. As a result, RMSE was mostly ...
First European pollen reanalysis for allergenic trees
Assimilation of the pollen concentrations was performed separately for every year and each tree. It resulted in a better representation of pollen observations (including those which were not assimilated) then ...
Modelling grass pollen load in temperate and Mediterranean European areas based on source spatial distribution
lands only explained about 10-20% of the variance of the mean grass API n, obtaining a non-coherent influence function. These results constitute valuable evidence of the land-use and vegetation types with ...
Impact of environmental nitrogen enrichment on birch pollen allergy
pollen production and/or properties, resulting in pollen collected from different environmental nitrogen deposition conditions exhibiting different allergenicity in sensitized patients. Methods: Fresh ...
Holography-based aerobiological monitoring: a 2-year intercomparison campaign versus the standard Hirst method in Brussels, Belgium
offline method can only provide results retrospectively, from 1 day to 1 week, and previous evaluation studies have shown certain limitations in terms of sampling efficiency and measurement accuracy. ...
Healthcare-Associated Infections and Antimicrobial Use in Belgian Acute Care Hospitals: Results of the 2022 ECDC Point Prevalence Survey
infections at 8.5%), surgical site infections (13.6%), urinary tract infections (18.5%), bloodstream infections (12.2%) and gastrointestinal infections (9.0%). Microbiological results were positive for 65.6% ...
