COVID-19 reached pandemic level in March 2020 and the number of confirmed cases continued to increase worldwide. The clinical course of the disease has not yet been fully characterized, and some specific symptoms related to smell, taste, and feeding behavior require further examination. The present study aimed to assess the presence of symptoms related to the feeding behavior occurred during and/or after COVID-19 in adults residing in Portugal and to link them to disease severity using a multivariate approach. Data were collected from May to September 2020, through a questionnaire answered online containing questions about general and specific symptoms before, during and after COVID-19. 362 participants were included: 201 were symptomatic, being 15 hospitalized and 186 non-hospitalized. Cluster analysis grouped the symptomatic non-hospitalized participants as mild and severe cases. For these patients, the most frequent symptoms related to the feeding process were smell disorders in 40% and 62%, taste disorders in 37% and 60%, and dry mouth, in 23% and 48% of the mild and severe cases, respectively. Dry mouth was significantly associated with difficulty to swallow, pain during swallow, choking when eating or drinking, and preference for mushy/pasty foods (p

The adsorption of mannitol and sorbitol on Au(111) has been followed by differential capacity measurements. Results obtained for the adsorption of these polyalcohols in dilute solutions of HClO 4 and NaClO 4 showed that the adsorption process could be described by a Frumkin isotherm, the parameters of which were determined and discussed. The values of the standard Gibbs energy of adsorption suggest physical adsorption of mannitol and sorbitol, without the existence of specific interactions of the adsorbed molecules with gold. The values of the interaction parameters are negative in both electrolytes, indicating a net attractive interaction in the adsorbed layer. There are noticeable differences between the values of the standard Gibbs energy of adsorption and of the interaction parameter for the two polyols, which have been interpreted in terms of the conformational properties of the two isomers in the adsorbed layer.
