Prevalence of healthcare-associated infections, estimated incidence and composite antimicrobial resistance index in acute care hospitals and long-term care facilities: results from two European point prevalence surveys, 2016 to 2017
and 117,138 residents from 2,221 long-term care facilities (LTCF) in 23 countries. After national validation, we estimated that 6.5% (cumulative 95% confidence interval (cCI): 5.4–7.8%) patients in ACH ...
Development and validation of chromatographic methods for screening and subsequent quantification of suspected illegal antimicrobial drugs encountered on the Belgian market.
validated. These methods could be used for routine analysis and enable a more in-depth characterization of SF-antimicrobials. According to their popularity as SF-antimicrobials, 31 antibiotics, 3 antibacterial ...
Monitoring of pyrrolizidine alkaloids in beehive products and derivatives on the Belgian market
detection were developed with a focus on very low LOQ s and validated for the analysis of 16 PA s and 14 PANO s in honey, honey based candies and snacks as well as beehive products based food supplements. ...
Development of a QuEChERS-Based UHPLC-MS/MS Method for Simultaneous Determination of Six Alternaria Toxins in Grapes
and anhydrous magnesium sulfate (0.5 g) was established to recover the six Alternaria toxins. After validation by determining the linearity (R2 > 0.99), recovery (77.8–101.6%), sensitivity (limit of ...
Combining primary care surveillance and a meta-analysis to estimate the incidence of the clinical manifestations of Lyme borreliosis in Belgium, 2015–2017
As both over- and underestimation of different clinical LB manifestations remain possible due to characteristics of the primary surveillance systems and the disease itself, future studies to validate ...
Development and validation of chromatographic methods for screening and subsequent quantification of suspected illegal antimicrobial drugs encountered on the Belgian market
(UHPLC- MS2) and diode array detection (UHPLC- DAD), respectively were developed and validated. These methods could be used for routine analysis and enable a more in-depth characterization of ...
