Background: Malnutrition is highly prevalent in medical inpatients and may also negatively influence clinical outcomes of patients hospitalized with COVID-19. We analyzed the prognostic implication of different malnutrition parameters with respect to adverse clinical outcomes in patients hospitalized with COVID-19. Methods: In this observational study, consecutively hospitalized adult patients with confirmed COVID-19 at the Cantonal Hospital Aarau (Switzerland) were included between February and December 2020.

We therefore studied the prevalence of deficiencies of eight different micronutrients in a cohort of hospitalized COVID-19-patients.
Methods: We measured admission serum/plasma levels of vitamins A, B12, D, and E, as well as folic acid, zinc, selenium, and copper in 57 consecutively admitted adult patients with confirmed COVID-19 and analyzed prevalence of micronutrient deficiencies and correlations among micronutrient levels.
Purpose: We evaluated whether a second semen analysis as suggested by the WHO Laboratory Manual for the Examination of Human Semen and Sperm-Cervical Mucus Interaction would improve diagnostic reliability in the evaluation of male infertility.
Materials And Methods: We analyzed a total of 5,132 semen samples from 2,566 men who underwent at least 2 consecutive semen analyses at a university fertility center. Reproducibility and correlation between the first and second analyses were evaluated for sperm concentration, motility and morphology according to the WHO criteria as well as the total motile sperm count.
