Assessment of the clinical and analytical performance of the Aptima SARS-CoV-2 assay using the VALCOR protocol.
of 180 clinical samples were tested with an addition of 40 diluted clinical specimens to determine the limit of detection. When compared to the standard comparator assay Aptima had a sensitivity of ...
Towards clinical breakpoints for non-tuberculous mycobacteria- Determination of epidemiological cut off values for the Mycobacterium avium complex and Mycobacterium abscessus using broth microdilution.
Mycobacterium abscessus (MAB) obtained by commercial broth microdilution (SLOMYCOI and RAPMYCOI) from 12 laboratories. Epidemiological cut-off values (ECOFF s) and tentative ECOFF s (TECOFF s) were determined by ...
Comparison of Serological Methods for Tick-Borne Encephalitis Virus-Specific Antibody Detection in Wild Boar and Sheep: Impact of the Screening Approach on the Estimated Seroprevalence.
prevalence in our sample set was 8.6% when determined by PRNT. When the screening approach of ELISA testing followed by PRNT confirmation was applied, a TBEV seroprevalence of only 2.0% and 1.7% was found. The ...
Environmental degradation and the increasing burden of allergic disease: The need to determine the impact of nitrogen pollution
result in an escalating burden of allergic disease. It is urgently needed to quantify the impact of nitrogen pollution on plant and pollen traits that determine allergenicity and symptom severity to ...

SARS-CoV-2 infection prevention and control measures in Belgian schools between December 2020 and June 2021 and their association with seroprevalence: a cross-sectional analysis of a prospective cohort study
the implementation of IPC measures as ‘poor’, ‘moderate’ or ‘thorough’. Saliva samples were collected from pupils and staff to determine the SARS-CoV-2 seroprevalence. To assess the association between ...
Estimating Years of Life Lost due to COVID-19 over the first two years of the pandemic in Cyprus: comparisons across areas, age, and sex
estimated. We aimed to determine YLL linked to COVID-19 over the first two years (March 2020–March 2022) of the pandemic in Cyprus, by areas, and by age and sex. COVID-19 YLL was estimated by multiplying ...
