Risk to human health related to the presence of perfluorooctane sulfonic acid and perfluorooctanoic acid in food

analytical results (PFOS n = 10,191 and PFOA n = 9,828). There were large differences between upper and lower bound exposure due to analytical methods with insufficient sensitivity. The CONTAM Panel considered ...

Sera from different age cohorts in Belgium show limited cross-neutralisation between the mumps vaccine and outbreak strains

tested if a difference in seroneutralising capacity against the vaccine and wild type viruses exists and if waning immunity could be detected. METHODS: In this study, 570 serum samples (age group 2-3y ...

Comparison of matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS) systems for the identification of moulds in the routine microbiology laboratory.

Microflex LT (MLT) — and the MSI  application. METHODS: Moulds were collected retrospectively and prospectively to display epidemiological diversity of a microbiology laboratory. All of them were identified ...

HIV testing within general practices in Europe: a mixed-methods systematic review.

a systematic review adhering to the PRISMA  guidelines. METHODS: The databases PubMed, Scopus and Embase were searched for the period 2006-2017. Two authors judged independently on the eligibility of studies. ...

Molecular epidemiology and antimicrobial resistance mechanisms of Campylobacter coli from diarrhoeal patients and broiler carcasses in Belgium.

patients. Both porA typing and MLST revealed a similar discriminatory power (0.969), which was the highest discriminatory power when compared to other methods. Minimum inhibitory concentrations against seven ...

Evaluation of three MALDI-TOF mass spectrometry libraries for the identification of filamentous fungi in three clinical microbiology laboratories in Manitoba, Canada.

Spectrometry Identification (MSI) online library, and compared those results to conventional (morphological) and molecular (18S/ ITS; gold standard) identification methods. All 3 libraries demonstrated greater ...

Prediction of Susceptibility to First-Line Tuberculosis Drugs by DNA Sequencing

accurately predict profiles of susceptibility to first-line antituberculosis drugs has not been clear. METHODS: We obtained whole-genome sequences and associated phenotypes of resistance or susceptibility to ...

Eight years after an international workshop on myotonic dystrophy patient registries: case study of a global collaboration for a rare disease.

collection methods (e.g. online patient surveys or clinician led) and have a variety of budgets (from being run by volunteers to annual budgets over €200,000). All registries collect at least some of the ...

Application of whole genome data for in silico evaluation of primers and probes routinely employed for the detection of viral species by RT-qPCR using dengue virus as a case study.

targeted nucleic acid regions. Whole genome sequencing allows to characterize and track such changes, which in turn enables to evaluate, optimize, and (re-)design novel and existing RT-qPCR methods. The ...

Relationship between mold exposure, specific IgE sensitization, and clinical asthma: A case-control study.

level of indoor mold contamination among mold-sensitized patients with asthma and nonsensitized patients with asthma. METHODS: A case-control study was conducted and several asthma severity markers were ...
