Evaluation of ECLIA antigen detection tests as screening methods for COVID-19 in comparison with molecular analysis.

Background: Data from literature shows that antigen tests are rapid and helpful tools for diagnosis of COVID-19.

Aim: This work aimed to evaluate the performances of the Elecsys SARS-CoV-2 Antigen test, in comparison to RT-qPCR, the gold standard.

Methods: A total of 110 swabs were tested; according to rRT-PCR, 76 were positive, and 34 were negative.

Human semen hyperviscosity: prevalence, pathogenesis and therapeutic aspects.

The aims of this study were (a) to determine the prevalence of subjects with semen hyperviscosity (SHV) in a large population of male partners of subfertile couples; (b) to identify any correlation between SHV and infections or inflammation of the genital tract; (c) to assess the effects of therapeutic approaches for treating SHV; and (d) to assess sperm kinetic parameters after successful treatment of SHV. A retrospective study of 1 833 male partners of subfertile couples was conducted. Next, clinical, seminal, bacteriological and ultrasound studies involving 52 subjects suffering from SHV were performed, and the SHV was classified as being mild (length of thread > 2 cm and 4 cm and 6 cm).
