Full Characterisation of Heroin Samples Using Infrared Spectroscopy and Multivariate Calibration

the collected spectral data and PLS modelling. These models were able to identify heroin correctly for 96% of the samples of the external test set with precision, specificity and sensitivity values of ...

The Belgian physiotherapy reimbursement criteria for fall prevention fails in screening appropriately fall-prone community-dwelling older adults

positive and negative predictive value and area under the curve (AUC) were calculated to ascertain which algorithm is more accurate. RESULTS: The database included a total of 94 community-dwelling older ...

Identification of Mycobacterium abscessus Subspecies by MALDI-TOF Mass Spectrometry and Machine Learning.

challenging. In this study, a collection of 325 clinical isolates of M. abscessus was used for MALDI- TOF MS analysis and for the development of machine learning predictive models based on MALDI- TOF MS protein ...

Predictive model for BNT162b2 vaccine response in cancer patients based on blood cytokines and growth factors.

accuracy. Amongst these, CRP showed the highest predictive value for poor response to vaccine administration. Importantly, this unique signature of vaccine response was present at different studied timepoints ...

The 2021 WHO catalogue of complex mutations associated with drug resistance: A genotypic analysis.

from 45 countries. For each mutation, a contingency table of binary phenotypes and presence or absence of the mutation computed positive predictive value, and Fisher’s exact tests generated odds ratios ...

Sensitivity of candling as routine method for the detection and recovery of ascaridoids in commercial fish fillets.

method whereby visible ascaridoid larvae are detected on a light table and manually removed. The aim of this study was to assess the sensitivity (Se) and negative predictive value (NPV) of this method. To ...

Nursing home residents with suspected urinary tract infections: a diagnostic accuracy study

The combined nitrite and leucocyte esterase urine dipstick test (one or both positive) had a 96.0% negative predictive value (95% CI: 80.5-99.3%). The sensitivity of a positive CRP test (≥ 5 mg/L) was ...

Retrospective evaluation of routine whole genome sequencing of Mycobacterium tuberculosis at the Belgian National Reference Center, 2019.

100% (pyrazinamide, PZA). The negative predictive value was above 95% for these four first-line drugs. A positive predictive value of 100% was calculated for INH and PZA, 80% for RIF and 45% for EMB. ...

Comparing health insurance data and health interview survey data for ascertaining chronic disease prevalence in Belgium.

both data sources were compared. Agreement was measured using sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) assuming BHIS data as gold standard. Kappa ...

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

other drugs or if they contained mutations of unknown association in genes that affect susceptibility to the other drugs. We simulated the way in which the negative predictive value changed with the ...
