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
of monitoring stations for birch pollen is good, although large differences exist across the 2013–2021 seasons, likely due to significant inter-seasonal variations in birch pollen production. For grass ...
First European pollen reanalysis for allergenic trees
assimilation of in-situ pollen observations of European Aeroallergen Network (EAN) in 34 countries. In the extended 4-dimensional variational data assimilation procedure, the total seasonal pollen emission ...
The search for the best airborne pollen monitoring locations
inter-seasonal variation in birch pollen production. For grass pollen, the average coverage is better, and the inter-seasonal variation much lower. Health Topics: Health and environment Santé et environnement ...
Attributing long-term changes in airborne birch and grass pollen concentrations to climate change and vegetation dynamics
time is highly associated with wind speed and precipitation. Introducing the inter-seasonal variation in birch pollen production during the period 1982–2019 intensifies the climate induced increase of ...
Gram-negative central line-associated bloodstream infection incidence peak during the summer: a national seasonality cohort study.
epidemiological studies should consider seasonal variation and climatological factors when preparing study designs or interpreting their results. Health Topics: Bloodstream infections Bloedstroominfecties ...
Long-Term Pollen Monitoring in the Benelux: Evaluation of Allergenic Pollen Levels and Temporal Variations of Pollen Seasons
a decreasing trend. The season timing of Poaceae showed a trend toward earlier starts and longer seasons in all locations. In all, these results show that temporal variations in pollen levels almost always ...
Seasonal variation of hospital-acquired bloodstream infections: A national cohort study.
temperature. Seasonality was most present among E. coli, K. pneumoniae, E. cloacae, and the nonfermenters. Gram-positive and pulmonary HABSI s did not demonstrate seasonal variation. CONCLUSIONS: Seasonality ...
Alternating patterns of seasonal influenza activity in the WHO European Region following the 2009 pandemic, 2010-2018.
reporting entity and season (weeks 40-20) for 2010-2011 to 2017-2018. We explored geographical spread using correlation coefficients. RESULTS: There was variation in the regional influenza epidemics during ...
Real-time prediction of influenza outbreaks in Belgium.
different epidemic seasons, providing weekly predictions makes it possible to capture variations in the ILI incidence. The confidence region becomes more representative of the epidemic behavior as ILI data ...
