Background:COVID-19 is fatal to patients with pulmonary hypertension (PH), so preventive actions are recommended. This study investigated the effectiveness of telemedicine and effects on quality of life (QOL) in the treatment of patients with PH.Methods and Results:Japanese patients with PH (n=40) were recruited from one referral center. Patient self-reported anxiety worsened significantly and elderly patients in particular experienced detrimental lifestyle changes under COVID-19. Telemedicine worked well to decrease the frequency of going out.Conclusions:Telemedicine is effective in reducing travel distances, and frequent remote interventions may be desirable for older, anxious patients.

Ovomucin, a hen egg white protein, is characterized by its hydrogel-forming properties, high molecular weight, and extensive O-glycosylation with a high degree of sialylation. As a commonly used food ingredient, we explored whether ovomucin has an effect on the gut microbiota. O-Glycan analysis revealed that ovomucin contained core-1 and core-2 structures with heavy modification by N-acetylneuraminic acid and/or sulfate groups. Of the two mucin-degrading gut microbes we tested, Akkermansia muciniphila grew in medium containing ovomucin as a sole carbon source during a 24 h culture period, whereas Bifidobacterium bifidum did not. Both gut microbes, however, degraded ovomucin O-glycans and released monosaccharides into the culture supernatants in a species-dependent manner, as revealed by semi-quantified mass spectrometric analysis and anion exchange chromatography analysis. Our data suggest that ovomucin potentially affects the gut microbiota through O-glycan decomposition by gut microbes and degradant sugar sharing within the community.
