Oral lesions in patients with COVID-19 hospitalized in an intensive care unit: a case-series study.

This study evaluated the presence of oral lesions in patients with COVID-19 hospitalized in an intensive care unit (ICU). Data included demographic, clinical, and laboratory information. Clinical assessment of the oral cavity was performed on the 2 nd and 5 th days of orotracheal intubation. Thirty-eight patients were evaluated and 16 (42.1%) presented oral lesions during their ICU stay. The median age and length of stay were 75 years and 15 days, respectively. Among the patients with oral lesions, ulcerative oral lesions were reported in 14 (87.5%) patients, of which 11 (78.6%) were found on the lips. This study highlights the importance of oral examination for patients admitted to the ICU with COVID-19.

Flexibility of Ballet Dancers in COVID-19 Pandemic: A Prospective Observational Study in Portugal.

The aim of this study was to verify how dancers' flexibility work has developed during confinement through four assessment moments: before, during (two times), and after the lockdown period. The sample was formed by 18 dancers from the Porto Dance Conservatory (Portugal) with an average age of 11.4 ± 1.4 years and 1.4 ± 0.7 years of experience. To assess the passive and active flexibility level, we used seven of the International Gymnastics Federation's recommended tests using main joints (i.e., hips and spine). The first evaluation was performed before the pandemic situation began in a training environment, and the second and third evaluation were performed during the lockdown, in home environment, and in virtual trainings. Finally, the last evaluation was carried out in a training environment after returning to face-to-face activities and with several rules such a social distancing and mask use. The results showed that significant improvements were verified in the flexibility level of the dancers from the first to the fourth moment of evaluation. In the current study, no statistical significance was noted for the decreased values of functional asymmetry between the preferred and non-preferred lower limbs. These differences may have substantial relevance for dancers' harmonious body development.
