Fuzzy-based PROMETHEE method for performance ranking of SARS-CoV-2 IgM antibody tests

This article belongs to the Special Issue Monitoring and Detection for SARS-CoV-2 and Its Variants.Antibody tests, widely used as a complementary approach to reverse transcriptase-polymerase chain reaction testing in identifying COVID-19 cases, are used to measure antibodies developed for COVID-19. This study aimed to evaluate the different parameters of the FDA-authorized SARS-CoV-2 IgM antibody tests and to rank them according to their performance levels. In the study, we involved 27 antibody tests, and the analyzes were performed using the fuzzy preference ranking organization method for the enrichment evaluation model, a multi-criteria decision-making model. While criteria such as analytical sensitivity, specificity, positive predictive value, and negative predictive value were evaluated in the study, the ranking was reported by determining the importance levels of the criteria. According to our evaluation, Innovita 2019-nCoV Ab Test (colloidal gold) was at the top of the ranking. While Cellex qSARS-CoV-2 IgG/IgM Rapid Test and Assure COVID-19 IgG/IgM Rapid Tester ranked second and third on the list, the InBios-SCoV 2 Detect Ig M ELISA Rapid Test Kit was determined as the least preferable. The fuzzy preference ranking organization method for enrichment evaluation, which has been applied to many fields, can help decision-makers choose the appropriate antibody test for managing COVID-19 in controlling the global pandemic

Assessment of UTI Diagnostic Techniques Using the Fuzzy–PROMETHEE Model

Accurate diagnosis of urinary tract infections (UTIs) is important as early diagnosis increases treatment rates, reduces the risk of infection and disease spread, and prevents deaths. This study aims to evaluate various parameters of existing and developing techniques for the diagnosis of UTIs, the majority of which are approved by the FDA, and rank them according to their performance levels. The study includes 16 UTI tests, and the fuzzy preference ranking organization method was used to analyze the parameters such as analytical efficiency, result time, specificity, sensitivity, positive predictive value, and negative predictive value. Our findings show that the biosensor test was the most indicative of expected test performance for UTIs, with a net flow of 0.0063. This was followed by real-time microscopy systems, catalase, and combined LE and nitrite, which were ranked second, third, and fourth with net flows of 0.003, 0.0026, and 0.0025, respectively. Sequence-based diagnostics was the least favourable alternative with a net flow of −0.0048. The F–PROMETHEE method can aid decision makers in making decisions on the most suitable UTI tests to support the outcomes of each country or patient based on specific conditions and priorities

Music effects on event-related potentials of humans on the basis of cultural environment

Auditory oddball responses were recorded from Turkish subjects in a silent environment or superimposed on white noise, or music played with violoncello or a similar music played with ney, a reed flute frequently listened by the Turkish population. P3 amplitudes with ney music in the background were significantly larger than both the white noise and violoncello backgrounds, The topography of the P3 response changed significantly between the ney and silent background conditions, indicating a relatively higher participation of frontal areas during hearing ney. Our results showed that hearing music of a familiar style increases the allocation of attentional resources during memory updating processes which is supposed to determine the P3 amplitude, and therefore showed the effects of cultural environment on the cognitive processes.
