Topical prebiotics/postbiotics and PRURISCORE validation in atopic dermatitis. International study of 396 patients

Aim: To investigate the efficacy and tolerability of a cream (Rilastil Xerolact PB) containing a mixture of prebiotics and postbiotics, and to validate the PRURISCORE itch scale in the management of atopic dermatitis.Methods: The study is based on 396 subjects of both sexes in three age groups (i.e., infants, children, adults) suffering from mild/moderate Atopic Dermatitis, recruited from 8 European countries and followed for 3 months.Results: The product demonstrated good efficacy combined with good/very good tolerability in all age groups. In particular, SCORAD, PRURISCORE and IGA scores decreased significantly over the course of the study. The PRURISCORE was preferred to VAS by the vast majority of patients.Conclusion: Even though the role of prebiotics and postbiotics was not formally demonstrated since these substances were part of a complex formulation, it can be reasonably stated that prebiotics and postbiotics have safety and standardization features that probiotics do not have. In addition they are authorized by regulatory authorities, whereas topical probiotics are not.

Mental Health Screening for COVID-19: a Proposed Cutoff Score for the Greek Version of the Fear of COVID-19 Scale (FCV-19S)

The COVID-19 pandemic elicited fear. The Fear of COVID-19 Scale (FCV-19S) is a newly developed self-reported measure, originally developed in Persian to assess COVID-19-related fear. To date, the scale has been translated and validated in 19 other languages, among which Greek. This study, conducted through an online survey, aimed to further explore the validity of the Greek FCV-19S version, as well as to identify appropriate cutoff scores. A total of 538 respondents completed the sociodemographic data sheet, the Generalized Anxiety Disorder 7-item scale, the Short Health Anxiety Inventory, and the Posttraumatic Stress Disorder-8 inventory. According to the results, a cutoff point score of 16.5 or higher revealed a significant predictive power for anxiety, health anxiety, and posttraumatic stress symptoms. Altogether, although the cutoff scores of the Greek FCV-19S version were explored to further evaluate the scale’s validity, they may facilitate discrimination of adults with extreme COVID-19-related fear from those with normal fear reactions.
