Extent and Effect of Covering Laryngeal Structures with Synthetic Laryngeal Mucus via Two Different Administration Techniques.

Objective: The first goal of this study was to investigate the coverage of laryngeal structures using two potential administration techniques for synthetic mucus: inhalation and lozenge ingestion. As a second research question, the study investigated the potential effects of these techniques on standardized voice assessment parameters.

Methods: Fluorescein was added to throat lozenges and to an inhalation solution to visualize the coverage of laryngeal structures through blue light imaging.

Effectiveness of psychosocial interventions for infertile women: A systematic review and meta-analysis with a focus on a method-critical evaluation.

Background: Approximately seven to nine percent of couples of reproductive age do not get pregnant despite regular and unprotected sexual intercourse. Various psychosocial interventions for women and men with fertility disorders are repeatedly found in the literature. The effects of these interventions on outcomes such as anxiety and depression, as well as on the probability of pregnancy, do not currently allow for reliable generalisable statements.
